颜色逻辑算法 [英] Color Logic Algorithm

问题描述

我们正在建立一个运动应用程序，并希望在应用程序的各个部分中加入团队色彩。

We are building a sports application and would like to incorporate team colors in various portions of the app.

现在，每个团队都可以使用几种不同的颜色来表示。

Now each team can be represented using several different colors.

我想做的是执行检查，以验证两个团队的颜色是否在一个特定的范围内，所以我不显示两个类似

What I would like to do is to perform a check to verify whether the two team colors are within a certain range of each other, so that I do not display two similar colors.

所以，如果团队1的主要团队颜色的值为rgb（255,0,0）（或＃FF0000），而团队2的主色相似，说rgb（250,0,0），那么我们将为其中一个团队选择不同的颜色。

So, if team 1's primary team color has a value of rgb(255,0,0) (or #FF0000), and team 2's primary color is similar, say rgb(250,0,0), then we would choose a different color for one of the teams.

如果可能，我可以采取什么方法来执行

If possible, what approach could I take to perform the check?

Here is a theoretical explanation

和算法C： / p>

And the algo in C:

typedef struct {
    unsigned char r, g, b;
} RGB;

double ColourDistance(RGB e1, RGB e2)
{
    long rmean = ( (long)e1.r + (long)e2.r ) / 2;
    long r = (long)e1.r - (long)e2.r;
    long g = (long)e1.g - (long)e2.g;
    long b = (long)e1.b - (long)e2.b;
    return sqrt((((512+rmean)*r*r)>>8) + 4*g*g + (((767-rmean)*b*b)>>8));
}
