The 8 circles are “metameric,” they share the same visual values. Well… they share color parameters: Hue, Brightness, Saturation, and are as I say “visually equivalent” at a certain distance (here something like 2-3 meters.) However, at a close distance they’re very different:

2      3      4

1                            5

8      7      6

Sample #1, two colors: cadmium Yellow n°2 + Ultramarine Blue greenish extra

#2, 3 colors: cadmium “cinnaber” Red + a mixture between Turkish Blue Light & cadmium Yellow n°2 + Ultramarine Blue greenish extra
