And I thought I could trust an expert doing years in LED displays...

So, this table does not show colours of same intensity?



Ok, but how could a sequence look like, that generates colours of same intensitiy?
Should each R G B value (running between 0...255) be corrected by the formula given by Per?


Each set of R G B coefficients multiplied by a certain factor, in that way, that the above sum is equal for each colour? Would that do the trick?

An example:
Red: 255 0 0 -> 0.3 x 255 = 76.5
Cyan: 0 255 255 -> 0.3 x 0 + 0.59 x 255 + 0.11 x 255 = 178.5
Corrected Cyan: 0.59 x 255 / 178.5 x 76.5 + 0.11 x 255 / 178.5 x 76.5 =
0.59 x 109.3 + 0.11 x 109.3 = 76.5

So, would RED (255 0 0) and corrected Cyan (0 109.3 109.3) now be of equal intensity?
