Now you might want to look again at these paintings of color relationships, this time more mindful of the degree of difference between the two colors in each painting—in all three color aspects.
You may select any of the sets or paintings listed at the right, which you saw without explanations, but this time the color descriptions will be displayed below each painting to help you objectify your viewing, should you want to try that.
Additionally, this second viewing sequences the paintings by decreasing luminosity (from left to right in the "set" groupings), whereas the first viewing was by decreasing intensity (from top to bottom). This additional viewing will give you another color dimension.
