Speak to me about yellow. . . .

[Renee Price]

Garth,

I had no idea that there was so much difference in brands of raw umber! The problem is, now you've started something. I am searching for a clean yellow. I've read about and used yellow ochre since day one, but it has a tendency to be muddy (W&N especially), and can dull colors. So in my search for a clean, warm, not glow-in-the-dark yellow, I have tried:
Maimeri Naples Yellow Deep- I love this color and use it for light mixtures, but is too light for lower values
Daniel Smith Yellow Ochre-the closest thing I've found but I'd like something cleaner
Maimeri Golden Lake- great yellow that does not turn blonds into greens but is a bit too orange and strong for flesh--but perfect for blond hair
Old Holland Naples Yellow Deep Extra- again too orange
Cennini Jaune Brilliant- a pretty & high pigment yellow, but still brighter than I'm looking for.

I'm looking for a clean, earthy warm yellow that isn't muddy or overpowering. Suggestions? Does one exist or am I doomed to mixing different yellows for eternity?

Thanks in advance,

Renee
