Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

You could find out by trial and error.
Blues are from 0 to 248 in steps of 8. Red and blue are 5 bit and green is 6 bit.

eg
for b% = 0 to 248 step 8 : cls b% : print RGB(0,0,b%) : pause 500 : next

When the colour is right note the last value of b%
If none of those are quite right add some red or green and try again.

MMBasic will try to map to the closest available colour, I think.

Again! I just use paint in windows.. The colour picker is pretty good.
I draw or copy a picture and use the pixel picker then look at the RGB values in the colour picker. ( just double click "Edit Colours")
I'd give my left arm to be ambidextrous
