Bob...I sent you a PM.
As to the "code" adjoining the color name....this is called the Color Inex Name, or CI.N. Short explanation...the manufacturers can give whatever name they want to their paint colors, so it's not always a guarantee that you're buying the color you think you are. I give the C.I.N. as a reference so people can verify the color they're buying. The C.I.N. is a standard system of labeling what pigment is in the paint you're buying. Each pigment (this is NOT that same thing as "color") has a unique number.
So, for example, Titanium White (PW 6) - a manufacturer may want to call it "Snow White"...that doesn't tell you much, other than it's "white"...look at the label and see that it's PW 6, and boom! You know it's Titanium White and you can buy with confidence.
An actual case in point...Golden offers a color called Raw Sienna...I checked the label and the C.I.N. was PY 43 - the C.I.N. for the YELLOW OCHRE pigment. Raw Sienna PIGMENT has a C.I.N. of PBr 7.
If you want to know more, I wrote a fairly comprehensive article on this (with examples) and posted it on my site:
"What is the C.I.N. and Why Do I Need to Know?"
As to the brands I use...I use Golden and Lascaux. But armed with the C.I.N. you can buy the same pigments in the brand you use, if they offer them (I think the exception would be the Transparent Oxides, and the Quinacridone Gold...I know Liquitex does offer Quinacridone Gold, tho).
That answer wasn't all that short, was it?
Bob...you mentioned you were color blind...armed with a working knowledge of the C.I.N. system, and you can at least BUY your pigments with confidence. The rest of us will help ya MIX 'em...lol...
