adjust combined rgb values with a formula block

[duncan]

im trying to adjust a rgb output from a lighting block using a formula and virtual inputs for the blue and green elements to tweak the colours - the lights i have dont have enough red, so i need to reduce the blue and green elements by a fixed but adjustable % via 2 virtual inputs

i can make it work by splitting the combined rgb using a rgb controller, and multiply each g and b output by an adjustment factor, then combine the rgb elements together again, but i would like to do it if possible using a single formula block - any ideas ?

The second formula in this article has dimming:

You can adjust the divisions/multipliers for each channel, giving different values.
