Paint names seem to only be a general indication of the color. And that drives me nuts too....as they vary so much from brand to brand.
I seldon buy a color I'm unfamiliar with unless I can unscrew the cap and look at it. I find that the color charts are seldom accurate either.
I use a very limited palette, but can't resist trying new paints. I have made some expensive mistakes
Thank heavens the manufacturers don't use color names like: Duck Yellow, Baby Toe Pink, Bubble Gum Blue, Early Sage, and Mushroom.
It is bad enough to have "Flesh" which doesn't match anybody's skin tone...ever.
