Recently this pill container ceased to be used for vitamins . . . which started me thinking of its use a travel watercolor palette. About the same time, I read an on-line interview with artist Joseph Zbukvic in which he mentioned John Singer Sargent's using only 5 colors
(I forget the name of the blog this was found on; the link was found on Facebook).
Zbukvic remembered Sargent using cadmium red, yellow ochre, ultramarine blue, and burnt sienna . . . plus a fifth color he could not remember.
(Looking at Sargent's paintings as well as a bit of googling, I wonder if cerulean blue was the other color?)
The interviewer then asked which five colors Zbukvic would choose --- He chose cadmium red, cadmium yellow, cobalt turquoise, ultramarine, and burnt umber. So I began playing with these colors in an extra sketch pad.
I tend towards cooler, more transparent colors. So I tried putting together five colors I thought would make the cleanest mixes, staying away from "mud".
Many artists prefer burnt sienna over burnt umber; I have tried both and still prefer burnt umber. I know it can be mimicked by mixing burnt sienna and ultramarine, but a burnt sienna color can also be mixed by adding a bit of yellow and red to burnt umber. And I just like the rich, chocolatey color.
After a bit more playing, I decided on quinacridone red, quinacridone gold, cerulean blue, ultramarine, and burnt umber. The plastic pill box holds six, so next I played a bit on the left to see what that sixth color might be. Still not sure . . . I like the subtlety of using just the colors mixed on the color chart. Maybe leave the sixth space open for now.
