Order matters: the first block is the lowest (closest to the beacon). Each block above is averaged with the running beam color, so later blocks pull harder.

How the beam color is calculated
The lowest stained-glass block sets the beam color directly. For every block above it, Minecraft averages the red, green, and blue channels of the current beam color with the new block's dye color. This running mean weights blocks placed higher in the stack more heavily, which is why reordering three or more colors changes the result. Exactly two blocks always average to the same color regardless of order.
