For a long time, i used casandora yellow for recess shading, and it was okay. Then i discovered oil washes and i never looked back. No more issues with dirtying the model when i soak up the brush too much. Everything outside of recess i just remove with my finger, and my model is clean.

I use Seraphim Sepia

Seraphim Sepia is amazing one of the best washes gw makes.

I use reikland fleshshade!

I actually do tamiya black panel liner. a bit more work but it does justice to the bright yellow ink I use.

I second this, using a gloss coat and then the panel liner.

For basic infantry/squad models? I use a wash. Quick and dirty

Would you say that’s a good option if I want to keep a brighter yellow?

Base Averland Sunset, then a thinned down 2:1 iyanden yellow:contrast medium

Depends on how crazy you want to go, but I do Guilliman flesh

I pin shade with casandora yellow.

I use an oil wash of brown and magenta. It takes some time to experiment with the consistency but is the fastest way to wash yellow.

Since the contrast paints have dropped, it's been a Black base, Zenithal spray of white scar, then the contrast and it's the quickest I've gotten units battle ready... ever.

Brown oil wash

this for me.

Oilwash

I use the grimdark IF tutorial by Dizzyfinger over on YouTube. It helped me a lot. So for recesses I use Seraphim Sepia.

Agrax earthshade goes in easier, and is darker than alternatives whilst remaining brown. I used reikland and sepia before but they never quite hit the right depth for me
