Do you know of any research into the quantity of a particular colour eg., yellow that is in a painting and whether that painting is one that gives pleasure?
I am not aware of any research on this topic. It would require some psychophysical experimentation to quantify the amount of “pleasure” (or other variable) produced by a range of paintings (and across a large population of observers) and then some image analysis to determine if there was a correlation between the amounts of any given color and the psychophysical results. Typically some sort of histogram analysis would be performed to measure the proportions of various colors in an image. This would require the definition of your color regions for categorizing the histogram (e.g. do you divide only by hue or do you use a 3D histogram). Even if there was a correlation, you would then need to explore the question of causation. Sometimes there is a correlation between two variables, but one actually does not cause the other.
