Gamut Masking (2011) James Gurney
I haven’t fully understood the use of a gamut mask before beyond simply choosing a palette. The same color scheme, as perceived by our eyes, can be cast into warm or cool light depending on the gamut mask which is chosen. The gamut mask will shift the colors within the frame towards less/more saturated depending on how warm/cold they are. E.g. an intensely saturated yellow will become quite grey under colder/bluer light.
I have potentially a lot of illustrations to paint over the coming weeks so this basic concept will be helpful.
