Like trying to understand the moon

And so when you're working with transparent materials, when you're looking at glass, plastic, ice, or water, you're looking at light itself. The light is coming through, and you see that cobalt blue, that ruby red, whatever the colour might be — you're looking at the light and the colour mix together. Something magical and mystical, something we don't understand, nor should we care to understand. Sort of like trying to understand the moon.
