What i want to do is probably a bit complex, i want the user of my program to be able to specify a set of 2D coords and a color for each coord. i found a program that can do it, but i don't know how...

that makes sense, so if i have two arbitrary points...

i can get the interpolation the distance between the first point and the newly calculated point over the distance between the first point and...

So, after a bit more seaching i have come across something that said to use Linear Interpolation, which i'm not sure how to impliment...

i get that the formula gives points on a line, and i can do...

OK, this is probably the wrong place for this question, but here goes nothing...

I want to know what math is involved in making a Color gradient (so i can program some myself). My goal for now is...
