计算RGB中的混合颜色

Question

我希望能够获取两个RGB-256矢量并计算它们的混合结果.此外,我希望能够为每个向量赋予不同的权重.我已经使用Word颜色板进行了实验,我已经看到了一些颜色根据加权平均值进行混合:

0.5*red(255,0,0) + 0.5*yellow(255,255,0) = orange(255,127,0)

其他人没有:

0.5*yellow(255,255,0) + 0.5*blue(0,0,255) = gray (127,127,127) 并不是 green (0,255,0)

是否有精确计算所有颜色的算法,或者我是否被迫使用查找表进行计算？

Answer 1

最好的解释是RGB颜色模型对我们人类来说有点不直观.
对于只知道如何通过混合不同数量的3种预定义颜色(红色,绿色和蓝色)来显示颜色的视频显示设备(例如监视器或电视)来说,这是完全合乎逻辑的.但这并不是你和我学会在小学混合色彩的方式.

在RGB中,白色表示为(255,255,255),相当于"全部打开".显示每个红色,绿色和蓝色分量的全部值,这会产生如此高的光强度,我们将颜色视为白色.相反,黑色(0,0,0)是显示装置的"默认"状态 - 当没有显示彩色光("0")时,结果是黑色或没有颜色.

当您完全混合黄色(255,255,0)和蓝色(0,0,255)时,您将获得由(255,255,255)或白色表示的颜色.将白色乘以0.5时,会得到灰色,因为255*0.5 = 127.

当混合红色和黄色时,它可能比你获得预期结果的任何异常更多.红色+黄色是(510,255,0),所以当你乘以0.5时,你得到橙色(255,127,0).

事实证明,你和我在小学学到的东西实际上更准确地称为减色模型,与RGB使用的加色模型相比.查看底部的两个图表,您将在左侧看到RGB颜色模型(添加剂),而在右侧看到CMYK颜色模型(减法).您应该能够立即看到问题.使用减色颜色模型将产生您想要的结果.

                                          

编辑:当然,说起来容易做起来难.也就是说,即使您采用CMYK颜色模型而不是RGB(已经很难,因为从RGB到CMYK的转换依赖于设备并且远非直截了当),这可能仍然不能满足混合纯蓝色的冲动( 0,0,255)纯黄色(255,255,0)并变绿.CMYK使用青色,品红色和黄色作为3原色,而不是红色,黄色和蓝色.如果您想以您选择的语言实施RYB颜色模型,那么您还有很多工作要做.

我不知道任何这样的算法可以逼真地组合RGB颜色.我试图在我的回答中解释为什么它是不可能的,或者至少是非常困难的.您可以将这个问题保持开放几天,看看是否有其他人有任何想法,但如果您需要坚持使用RGB模型,我会继续在该查找表上开始.;-)

Answer 2

基于此记录的响应和此算法感知的响应，我尝试了一个简单的界面，使用加法和减法方法来混合颜色。

您必须确认 RGB 和 CMYK 的原色为您提供第一个响应图中的间色：

• 红色 + 蓝色 = 洋红色（基于添加剂）
• 黄色 + 青色 = 绿色（减色）
• 等等 ...

Answer 3

我需要为我的一个图书馆做同样的事情。我应用了本文建议的方法，结果是相当可以接受的。

这个过程非常简单。它需要将颜色转换为 RYB 颜色空间，进行混合，然后将结果转换回 RGB。他们提出了一个与下表一致的转换方程：

RGB颜色	RGB 值	红黄蓝值
黑色的	回复: 0 | 重力：0 | 乙：0	回复：255 | 是：255 | 乙：255
红色的	回复：255 | 重力：0 | 乙：0	回复：255 | 是：0 | 乙：0
绿色的	回复: 0 | 重力：255 | 乙：0	回复: 0 | 是：255 | 乙：255
蓝色的	回复: 0 | 重力：0 | 乙：255	回复: 0 | 是：0 | 乙：255
黄色的	回复：255 | 重力：255 | 乙：0	回复: 0 | 是：255 | 乙：0
品红	回复：255 | 重力：0 | 乙：255	回复：255 | 是：0 | 乙：127.5
青色	回复: 0 | 重力：255 | 乙：255	回复: 0 | 产量：127.5 | 乙：255
白色的	回复：255 | 重力：255 | 乙：255	回复: 0 | 是：0 | 乙：0

以下是建议的公式（将TypeScript代码视为伪代码）：

type RYBObject = {
    r: number;
    y: number;
    b: number;
};

export const rgbToRYB = (r: number, g: number, b: number): RYBObject => {
    const Iw = Math.min(r, g, b);
    const Ib = Math.min(255 - r, 255 - g, 255 - b);
    const rRGB = r - Iw;
    const gRGB = g - Iw;
    const bRGB = b - Iw;
    const minRG = Math.min(rRGB, gRGB);
    const rRYB = rRGB - minRG;
    const yRYB = (gRGB + minRG) / 2;
    const bRYB = (bRGB + gRGB - minRG) / 2;
    const n = Math.max(rRYB, yRYB, bRYB, 1) / Math.max(rRGB, gRGB, bRGB, 1);
    return {
        r: rRYB / n + Ib,
        y: yRYB / n + Ib,
        b: bRYB / n + Ib
    };
};

type RGBObject = {
    r: number;
    g: number;
    b: number;
};

export const rybToRGB = (r: number, y: number, b: number): RGBObject => {
    const Iw = Math.min(r, y, b);
    const Ib = Math.min(255 - r, 255 - y, 255 - b);
    const rRYB = r - Iw;
    const yRYB = y - Iw;
    const bRYB = b - Iw;
    const minYB = Math.min(yRYB, bRYB);
    const rRGB = rRYB + yRYB - minYB;
    const gRGB = yRYB + minYB;
    const bRGB = 2 * (bRYB - minYB);
    const n = Math.max(rRGB, gRGB, bRGB, 1) / Math.max(rRYB, yRYB, bRYB, 1);
    return {
        r: rRGB / n + Ib,
        g: gRGB / n + Ib,
        b: bRGB / n + Ib
    };
};

您可以使用此方法来混合颜色：

const mixColors = (c1: RYBObject, c2: RYBObject): RYBObject => ({
    r: Math.min(255, c1.r + c2.r),
    y: Math.min(255, c1.y + c2.y),
    b: Math.min(255, c1.b + c2.b)
});

// color1 and color2 are the input colors in the shape of RGBObject
const mixedColor = rybToRGB(
    mixColors(
        rgbToRYB(color1),
        rgbToRYB(color2)
    )
);

在这里您可以看到使用我构建的库的结果，该库使用上述方法来实现混合：

const { ColorTranslator, Mix } = colortranslator;

const mixes = [
  '#FF0000',
  '#FFFF00',
  '#0000FF',
  [1, 3],
  [1, 2],
  [2, 3],
  [1, 2, 3]
];

const paths = document.querySelectorAll('#planes path');

paths.forEach((path, index) => {
    let color = '#CCCCCC';
    if (mixes[index]) {
      if (typeof mixes[index] === 'string') {
        color = mixes[index];
      } else {
        const colors = mixes[index].map((i) => mixes[i - 1]);
        color = mixes[index] = ColorTranslator.getMixHEX(colors, Mix.SUBTRACTIVE);           
      }
    }  
    path.setAttribute('fill', color);
});
