How to find all the colors between two colors?

At the beginning, we have two colors in RGB, and a number, for the intermediate colors between them. Method must return an array with required colors. Strongly need help with an algorithm.

Answer 1

Suppose we have 2 Colors (R1,G1,B1) (R2,G2,B2) and N number of intermediate colors:

for i from 1 to N:
    Ri = R1 + (R2-R1) * i / N
    Bi = B1 + (B2-B1) * i / N
    Gi = G1 + (G2-G1) * i / N
    AddToArray(Ri,Gi,Bi)

Is that what you are looking for?

PS: I would recommend using the HSL color space instead of the RGB if you want to have a more natural color gradient.
