例子: (0,0,255) - >“蓝色” (255,0,0) - >“红色” (128,128,128) - >“灰色” 填充“已知”颜色列表。 对于每个已知的颜色计算: rgbDistance = Math.abs(myColor.getRed() - colorI.getRed() + Math.abs(myColor.getGreen() - colorI.getGreen()) + Math.abs(myColor.getBlue() - co...
The resulting luminance value is usually in the range of 0 to 255, which is suitable for grayscale values. Let's apply this formula to the red color FF0000 [255, 0, 0]: Luminance (Y) = 0.299 * 255 + 0.587 * 0 + 0.114 * 0 Luminance (Y) = 76.455 When rounding to the n...
