一开始，我们有RGB的两种颜色和一个数字，以表示它们之间的中间颜色.方法必须返回具有所需颜色的数组.强烈需要有关算法的帮助.

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.

推荐答案

假设我们有2种颜色(R1，G1，B1)(R2，G2，B2)和N种中间颜色:

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)

PS:如果您想要更自然的颜色渐变，建议使用HSL颜色空间而不是RGB.

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