as a counterpoint on the color mixing deal,,,,I used to mix colors, but, that was in my Floquil and Enamel days, I didn't want to have to do that anymore after changing paint types
since switching to Acrylics,,,,,,,I just went and bought paint one bottle of each color at a time (later buying more of the "right" ones),,,,,,,and matched them up to actual standards,,,,,relabeling the caps as I came across "matches" that didn't match
I now have 352 matches to standards, and only have 10 colors that I might have to mix (no one makes those 10 colors in any model paint range, although some were labeled as matches)
