颜色渐变的数学 [英] Maths for color gradient

问题描述

是否有任何用于制作（简单）颜色渐变的数学？
我正在寻找一个简单的梯度方法。
不是特定的语言。只是数学的颜色。

Is any Maths for making a (simple) color gradient? I'm looking for simple methods of making a gradient. Not in a specific language. Just the maths of colors.

推荐答案

一般来说，颜色渐变是一种线性函数，例如，如果要生成从红色（100％，0％，0％）到蓝色（0％，0％，100％）的渐变，则可以将每个颜色值从其初始值扫描到其目标值。

In general, a colour gradient is a linear function for easing from one colour to another. For instance, if you wanted to produce a gradient from red (100%, 0%, 0%) to blue (0%, 0%, 100%), you would sweep each colour value from its initial value to its target value.

在渐变的中间，颜色值将等于第一种颜色的50％，添加到第二种颜色的50％。在此示例中，您最终会显示（50％，0％，50％） - 等于紫色。

At the middle of the gradient, the colour value would be equal to 50% of the first colour, added to 50% of the second colour. In this example, you'd end up with (50%, 0%, 50%) - which is equal to purple.
