Everytime I've tried painting yellow, it has come out very blotchy and it hasnt dried smoothly.
I actually paint yellow Totally the Wrong Way, taking advantage of the forgiving nature of 6mm models - I start with a black basecoat and drybrush a few (thin, so it doesn't get chalky) coats of white over that, so just the nooks and crannies are still black, then build up the yellow from there. That
might work at 28mm, but I'd probably just start with a white undercoat. At any rate, the yellow goes on like this:
Two or three coats of very thin yellow. It'll look a bit streaky here, and you have to be careful to let each coat dry completely before moving on to the next, so it doesn't get even more lumpy and brush-strokey.
A thin wash of a mix of brown ink and yellow paint to create some shadow. This also starts to even out the streaking.
From here I build up one or two layers of yellow highlights, mostly just with the aim of killing some of the dull the brown brings. (I might be tempted to do more than that in 28mm.) I use a mix of golden yellow and a Vallejo lemon yellow I have. Very thin paint, and ending up with nothing too bright - my smallest, brightest highlights are still not even straight lemon yellow, very thin. No white in the mix at all. Again, this step does a lot to even out blotchiness. I usually take the fact that the color looks even as a stopping point.
In fact, I'll often think the yellow looks like complete blotchy crap until I get all the way to the final stages, when suddenly it looks quite nice - I remember seriously thinking about scrapping the Warlock titan and starting over fresh from a white undercoat at least two or three times as I was painting it.
The number one take-home lesson, I guess, is always use multiple coats of very thin paint at every stage, and build up lots of coats.
