Brain challenge: allocate #00ff00 (green) to another RGB colornumber

Hi all,

I'm looking for a solution for my problem. I really hope someone can help me out / point me in the right direcion here.

The problem: an application (coded in C++) has hardcoded which colors it can use. Everything drawn by the code is green (#00FF00). The developers choose to include all combinations of FF and 00. So, red, yellow, magenta, green, etc. These one can choose from.

However, I need to have a customized color in this application (0, 255 , 191).

So the problem to solve is: I need a hex assigned value (#00FF00, green) to represent another color, but without changing this hexcode! I want this hexcode (#00FF00) to represent the color: 0, 255, 191)

So, before the app starts reading all variables and declares all constants, a want to redesign the colorpalette it uses, so whenever the hexcode #00FF00 is called, it returns the RGB value of 0, 255, 191

Any clues?
Fan

Color pallettes were used many decades ago in some screen modes.
I don't think you can do this substitution likely now, but I may be wrong.

hi FanOfBMS432

In many ( perhaps all ??) computer languages green is represented this way.

So I suspect it is a standard to make it easy to generate colours correctly on the screen when the code is sent to the graphics sub-routines.

So I would suggest you find a way to program the change in a variable you want so the correct colour is made rather than changing the palette.

Some sort of Look Up Table perhaps?
