I am learning software development and I need to do something that requires some pretty good mathematics I think. I am not very good and been working to solve this problem for a few days now, any help is appreciated.

Here is what I am doing:

I need to find a way to convert pixel colors (rgb) into a 2d xy coordinates.

I know that the perfect red (255, 0, 0) color is at this position:

rx = -26;

ry = -100;

I know that the perfect green (0, 255, 0) color is at this position:

gx = -50

gy = 76

I know that the perfect blue (0, 0, 255) color is at this position:

bx = 62;

by = 10;

I know that white (0, 0, 0) is at this position:

wx = 0;

wy = 0;

I know that black (255, 255, 255) is at this position:

blx = 0;

bly = 0;

Now I need to figure our the formula to convert something like:

(234, 23, 54) to a X Y position.

This is an image of what I am developing, I have something that works right now but the formula is not right.

Can this be done ? Impossible maybe ?

Thanks a lot of the help ! *pulling hair* :)
