Distinctions in color is what Thrawn uses to analyze art of cultures. His red-in-red eyes and sclera see several wavelengths that non-Force sensitives cannot see.

Combined with the root parts of paint ingredients for the paint and color, Thrawn can decipher, why the painting was created and the mood of the artist. There is also brush stroke and art structure.
