In these images we have two portraits, the first by Sargent and the second by Solomon. Both contain pretty simple analogous color schemes but, as the shape of the color map shows, with diferent levels of saturation mostly within the yellow-orange spectrum. So, along with the master study course I am preparing for I am looking at different ways to assess and analyze the color in a portrait. The difficulty translating oil paint into digital color expressions is that most color in an oil painting is a result of the mixing of literal physical pigments rather that selecting a pixel of color (as it is done digitally). So I developed this color wheel to simulate the neutralization of a hue by mixing with it's complement (red mixed with green for instance). What I can't figure out how to do is how to show the values as well without making the model 3D... Still working on that. Eventually I want to perfect the analysis model so that I can compare the color expressions of artists throughout their career and also to compare between artists. It could also be use to compare color expressions between eras- What color world was available to Velasquez via the pigments availabel at that time vs. as artist with all of the modern synthetic pigments we have today...
