these triangles are from way back when we were working on color wheels. i took photographs from slightly different angles, with and without a flash and with incandescent light turned on/off. it was dark outside at the time.
For each photo, I selected a pixel in an area of each triangle that i thought best represented the overall color in the photo. The three on top are relatively the same, with just a slight difference in angle with light and a flash. The fourth is with light and no flash; the fifth image is no light and the flash on.
I copied the swatches at the bottom from the sets next to each case.
So it’s sort of a light-based color study with the ColorAid triangles.
This photo reminds me of a graphic design trend from the 80s
