我们正在建设一个体育应用程序，并希望将球队的颜色在应用程序的各个部分。

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

现在每支球队可以重新$ P $用几种不同的颜色psented。

Now each team can be represented using several different colors.

我想要做的是进行检查，以验证这两个球队的颜色是否在一定范围内对方的范围内，所以，我不显示两个相似的颜色。

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.

因此​​，如果队1的主要球队颜色有RGB值（255,0,0）（或＃FF0000），和2队的主要颜色是类似的，说RGB（250,0,0），然后我们会选择不同的颜色的球队之一。

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.

如果可能的话，我有什么办法可以用来执行检查？

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

感谢

推荐答案

下面是

和在C算法中：

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));
}
