Color
Color is a funny thing: it is both objective and subjective at the same time. We can measure it with a Munsel chart, but at the same time, we experience it differently depending on light level, light warmth, background color, and our own cultural context. The black-blue/white-gold dress controversy is proof enough of the fickleness of color perception. 3D modeling allows us to play with different light levels, warmths, and angles, to help visualize the diversity of color experiences - even of a single object!
