Re: tricolor gum question - yellow



Cut your pigment in half.  With some yellows, I may even
dilute 1+30!  Don't have my calculations in front of me but
I know PY150 is a strong yellow and needs quite a bit of
dilution. Never have used cad yellow tho I like its
color..because I don't do yellow as a first coat ever
because it's hard to eyeball registration with it.
