Re: my pigment dilutions
M. Graham PY 151 and Maimeri PY 175 I mix up to the same dilution: 15ml in 60ml total volume. PY 175 is a tad paler at that strength and a tad cooler, but not enough for me to think the dilution needs changing. And both are weaker than the PY 150 Nickel Azo Yellow. But this, of course, all depends on your particular brands. Plus, Schmincke has 16ml tubes if that is your brand of choice, vs 14 or 15ml.
