Is there a distinction between "owning" a digital color, a color of light or a color of object? The background of this question is that an infringement lawsuit will have to test for some kind of "equality" between colors -- possibility of confusing the two has been mentioned in another comment. However, a digital color gets converted to a color of light in a way that is highly dependent on the monitor it is displayed on, and color-of-light vs. color-of-object aren't really comparable at all: An object is only visible under an external light source, which always has an intrinsic color and therefore always affects the color-of-object seen by an observer. How would this get dealt with in practice?
