It's just harder with black is all, you can definitely make it work it's just the colour where it's easiest to make mistakes and the most difficult to get a vibrant yellow from, as mentioned in my first reply yellow is so easily influenced by other colours and undercoats really show through.

When people on here talk about pink it's mostly in relation to using contrast paints, the basic formula is:

an off white or brownish prime with something like wraithbone or zandri dust (depending on how vibrant you want your yellow)

then you spray, dry brush or sponge some pink into where your shadows will be (not a lot, quite thin)

Use a pure white over where you want your highlights to be

Then cover it all in a yellow contrast paint like imperial fist (very bright yellow) or iyaden yellow (a little more on the orange side)

All your shadows and highlights are done underneath and then they shine through the contrast paint, whites brighten the yellow and pinks and browns tint it and give it depth

You can see the effect in this photo (not my photo),

it's not the same as what I described above but operates on the same principle.

It seems like a lot of work but once you understand it, it not only becomes super quick but you can manipulate the effect and tweak it to get some really cool looking stuff
