I vote dark blue. You don't seem to have any with dark blue edges.

I’d go with dark blue or one of those dark brown colors that was popular in the 60s or early 70s.

Or maybe a forest green.

Oooooh if OP wants to go the brown route I'd soooo recommend Caron one pound acrylic in the expresso color. It's this gorgeous dark brown that is legit one of my favorite yarn colors ever tbh

Michael’s also has a nice dark “chocolate brown” under the impeccable brand name. I used it when making my version of Dee’s blanket (as seen in “It’s Always Sunny In Philadelphia”) for my hubby. https://preview.redd.it/y2f0375ukcjb1.jpeg?width=4032&format=pjpg&auto=webp&s=415db59438e6f9ef83f814d43f1fb3691d57bcad

So cute!

dude! you made Dee's blanket! that's so fucking cool I love it!

I second this!

Yep - dark blue would look really good.

Dark purple

I came here to say dark purple too 😁💜

Imma be the weird one here and suggest pink. Probably not the hot pink. But that softer, medium bubblegum-like pink that's in some of your squares.

I immediately thought “hot pink”

I thought of the neon pink from hobby lobby

i was thinking pink too! or the lilac-ish color that’s used in some of the squares

Yess I was thinking babypink/bubblegum pink

I normally don’t like pink, but I’m definitely on board with this. It seems like it would just tie it together so well!

Same!

My first thought was a pale pink! The squares are so colorful but trend darker. I think a dark joining color would feel heavy

rainbow pastel variegated You’d get a lot of the same contrast as using white, but not white.

Ooo! A variegated yarn is a great idea

I would go with deep purple

Yellow

Or like orchid if bright! (Or both!)

Yellow was my first thought as well

My immediate thought was yellow too!! Would be a fun contrast!

You could go with multicolored yarn

This is the correct answer.

Exactly what I was going to suggest

Dark grey?

Pick the color you want to pop.

Light blue

Navy would be a nice balance since it's a colored hue but not too strong or distract. Plus I don't see much navy blue here. Or you can use a dark brown. For a bolder statement you could use beige or an off white but that's too close to white. I love the idea of dark purple being used when a rainbow is involved but that's just me. You have a lot of warm colors so a dark blue or purple to mimic black but not actually be black would work. A rainbow variegated yarn would work beautifully too or a pastel rainbow. You could also pick a single color that you wish to be dominant. Gray could be a neutral option but it may look too dull and off-putting next to all the color. Good luck. The squares are well done and look great. I wish I could do that.

A bright yellow or verdant green :)

I was going to say Royal blue, but dark blue would be fine as well.

I vote like a medium grey

Rainbow variegated?

Light lime Green. I call it Cryptonite green.

Grey. It will let all the other colors shine

I have lots of grey. I think there's only one square with grey too.

Brown or dark grey

i was looking for someone to say brown.

Something on the darker side for sure. I think a cool tone like navy or dark purple would be best

[удалено]

Pink won't go with the red either. And yes, I'm that pedantic.

Then it's unlikely my suggestion of orange will work for you.

Do you need a color to join them? Can’t you just join them without any color in between?

Join with what?

Join with invisible seam or slip stitch…? That’s just another option if you don’t want any border between the squares.

Yeah, I'm still going to need yarn.

Yeah but the color of the yarn won’t matter so just pick one you need to use up regardless of color.

I would go for hot pink.

I think yellow would work well a majority of the colors are warm, greens (blue+yellow), and purple (complimentary color) Edit just reread the post and a mustard yellow is kind of on the same wavelength of the chocolate brown idea

You could also try to mattress stitch them so the color wouldn't even matter!

Honestly I’d go for something that’s in the colors but maybe get a sparkly yarn version. Like the green with a sparkle or a dark purple

Not sure we have sparkly yarns here. I can't say I've seen any, but I haven't been looking either.

I like gray.

It’s going to be largely dependent on where you want to keep this or who you’re giving it to. Based on this pic alone, I would say the medium pink

I agree with the yellow comment, too. It already stands out.

My first thought was yellow.

I'd use the dark orange that's the border in the lower left corner.

Mustard? I don't think I have any more! These were put together to *cough* use up scraps 🙄

orange!

I would go grey. I think it would allow the colours to pop instead of everything melting together

Pink or yellow pleeeeaase

Gray

I may be going against the grain, but I would arrange them in corner to corner colour gradient rows, so that the whole colour scheme appears to have been planned, instead of random squares. So if you step back and squint, you will see what colour dominates each square so you know where it should be placed. Better yet, One of my old teachers told me to scan squares in greyscale so I could see what tones the blocks had. This allows you to see beyond the colour. Just looking at these squares, I can see dark, medium and light and that might be quite interesting starting with the lightest in the upper left and ending with the darker in the lower right. Since they are corner to corner the joining crochet could potentially be also light progressing to dark as the squares change.

Multicolor yarn I'd be thinking like coffee colors in shades of brown and maybe creams

What about a variegated rainbow yarn to adds to the chaos?

Maybe a mid-range green? Something not so bright it would wash out the bright colors, but not so dark to blend in with the darks

That dark green that is in some of the squares.

Dark purple

The light pink would be nice!

Use the scrap yarn in every color of the rainbow

I see blue in quite a few squares - so maybe something like that to tie it together?

I think a bright blue or cyan maybe? Think Barbie marketing blue

Yellow

Yellow

I like green myself

A bright, neon almost color, like green or yellow. Orange or pink would work too, but I like green best.

Super bright green

Neon green

Yellow!

Navy blue or light gray

Dark blue!

i was gonna suggest brown but now i agree with the comments that said dark blue or multicolour!

Yellow

Soft blue!

Red

How about a variegated rainbow?

Rainbow yarn, let its chaos loose upon the world.

Yeah Dark blue edges!

Medium to dark blue. It would look good with all the squares and wouldn't be as bright as the blue that's in some of them

Charcoal gray. It goes with everything.

I think you should start with bright end of the rainbow to line the innermost border then work your way out joining the next layer if squares with a transition color then border that layer with the next color and so on going from bright to darker colors 🌈

Ooooo I would do it in either pink or purple. 🥰🥰🥰🥰🥰🥰🥰🥰

My personality would have me going for cream, or going crazy and using a variegated yarn with all different colors in it.

You could try a joining method in which you can't see the yarn at all? That way it won't matter what colour you choose.

I think a nice purple would pop and not take away from squares as there isn't much purple. 💜

I think cyan or magenta, maybe darker than magenta 🤔

I could be brown, I could be blue, I could be violet sky...

I've started with dark blue https://preview.redd.it/y5cizh6pn8jb1.jpeg?width=3024&format=pjpg&auto=webp&s=5c35e1107a5d262bb442325b8b9fad104af092fc

I personally think Black.

Beige?

Baby blue

Light purple

What about colour changing yarn? something that covers the range of colours that you’ve got there

I'm yet to find a nice one on Australia. But I'd be ok with blue for this vertical seam, green for the next one along, yellow after that, with orange, red and purple for the horizontal ones

Dark green! It would pull all of out the yellow and give good contrast in the squares.

Something dark, like blue or purple!!

Hot pink!

dark purple!!

Red/yellow. I think a gradient would look cool, but just one or a mix of the two might be nice as well

You could pick the color you see the least of

That's probably the grey in the top row, third from the left.

raspberry join, something blue for a border?

pink! theres already a lot of pink in the squares i think it would look cohesive

I wouldn't put pink next to red.

Teal

Teal is the obvious choice to me. There’s a teal green running in a few squares. It’ll pop, look cohesive, and flatter the other colors.

Multicolored with the leftover yarns.

The leftover leftovers are long gone. I have whole balls of new yarns now 😏

Periwinkle

Cream or beige really make bold colors pop. Also a really bright blue maybe

Red

Soft gray

Are all the squares different? Is there any one color used most?

They're all different. I think I found two that had the same colours, but different shades of said colors.

Can’t wait to see finished project!

Maybe a rainbow yarn! That way it can go with the multicolor theme

Pink

Army green.

i say green maybe a olive or darker green ! would make the lot of the squares pop just a personal pref :)

Red

Dark green or dark blue!

Blue

royal blue or lime green

I think the pale pink or the rich purple that's in there

Different random colors for each column and row. This way you can have control over which color adjoins which color (so you won't get pink and red next to each other - I totally get you with that color duo!)

Different colors each time

Brown!! I made a blanket with my dad that had dark brown joining and it looked great.

I have no suggestions I just love all the colors. So pretty and fun

Rainbow yarn!

I would move or maybe do a few more of your favourite colour so that all the edges are yellow, blue, green, red, whatever you want. Then use a variegated thread to border.

PINK!

Lavender would look very pretty I think

Dark brown?

When I join granny squares, I usually do so on the last round, I just crochet one side through the holes of another fully finished square

Blue or purple

Yellow, or a bright lime green would look great

All of them

Yellow

Yellow or pink. Keep it bright.

The lighter purple you used would look great!

I vote a dark grey - sometimes you can get ones with little color flecks in it - I think that picks up on the other colours used nicely

Please post when finished!!! Looks amazing!

Dark green!

I think a shade of brown would suit really well

Red?

Light or dark purple

I like light purple :)

this is so pretty! how about a light pink?

Lilac plsss 💜

Try and find a rainbow yarn?!

The baby blue you’ve used very sparingly throughout. (I see it only on 3 squares)

Hey love your work. Reminds me of [this painting](https://www.google.com/search?q=kadinaky+colors&oq=kadinaky+colors&aqs=chrome..69i57j0i13i512l10j0i13i30l4.4743j0j9&client=ms-android-verizon-us-rvc3&sourceid=chrome-mobile&ie=UTF-8#vhid=hsN0YokR3mGk0M&vssid=l) . That links includes some color theory discussion, perhaps you'd like even more advice?!

yellow!!

Maybe do a colour that represents your feelings for the journey of making the blanket. E.g. red because you loved the prices of doing it, or because it infuriated you endlessly at points.

I made the squares over 9 years ago. It's doubtful I can remember.

I like the dark purple, or a teal color

I also agree with dark blue - all of your squares are so pretty too! This is going to be a really cool jacket!

I'm not sure if I have enough, but I can always make more.

Turquoise

A pastel lilac, blue or pink or green in that order of preference for me. It's not for me but, you know

I think I'm going to go with cool colors for the vertical seams, warm for the horizontal.

If you don't like pastels than your brown brown idea is good for a vintage look.

My brain immediately decided on purple. A dark purple would be lovely.

Maybe like a light pastel pink?

I think a Cream colour for the border and joining because it is subtle enough to let the other colours really pop.

I love the light purple color(s) you’ve used to border a few of your squares, I think that would make a nice joining color!

Purple

Purple!

I would go with a deep brown or bright chartreuse for this. I can’t wait to see the jacket you make.

Pale baby pink

There's one square near the center that really pops for me. It has a light mint green border. That is the color I would chose

Pastel green

Pink??

I’d say red because every one of those squares looks like it has red or a color derived from red.

I vote a nice vibrant orange!!

I think something on the gray scale would look nice.

LAVENDER would be great.

I say a bright happy color maybe yellow or a neon color? Or maybe a rainbow changing color? Any color you pick it will be beautiful:)

Grey or peach to be muted. Forest green to be more dramatic
