Below are azaleas from the same area of the bush, but under different colors of light. Those on the left are on my dining table and on the right, on the azalea bush outside. We might note here that the camera interprets the colors differently from how my eye sees them, nevertheless, it records something about how the color of light changes the color of everything it illuminates.
Taking my experiment a bit further, I took four photos of one the inside blossoms. For each shot, between the light source and the flower I held a different colored transparency, changing the light color. The changes are subtle, but seeing and translating these nuances can mean everything to color harmony in our work.
