I assume that the colour values are specified in terms of OpenGL colours. If
so, the values are not to be given in RGB-bytes, but in floats or doubles in
the range from 0.0f - 1.0f. That is
(1.0 0 0) for red
(0 1.0 0) for green
(0 0 1.0) for blue
Specifying larger values will result in a cut-off, so
(10 0 0) => (1.0 0 0)
(255 0 0) => (1.0 0 0)
so this is the reason why you always get the same colour appearance.

So try something like:

self set-color to (0.0, opinion * (1 / 10), 0.0).


Hope I could be of help,
