Android 什么是'；W'；RGBAW中与颜色矩阵相关的值？

我知道矩阵[0-3]值是R'的RGBA值，但我能找到的矩阵[4]“W”值的唯一描述是它被用作占位符。有人能提供关于如何使用“占位符”W值的上下文吗

float[] matrix = {
            1, 0, 0, 0, 0,
            0, 1, 0, 0, 0,
            0, 0, 1, 0, 0,
            0, 0, 0, 1, 0,
    };

最佳，

以RGBAW为基础，代表红、绿、蓝、琥珀白

根据：

什么是RGBAW？ RGBAW是指驱动Luxli灯的LED矩阵的设计，它是 Timpani与大多数其他1x1照明解决方案的区别。昔日的LED面板 通常有两种不同的LED颜色，日光平衡或钨丝 平衡的，或两者的组合，用于双色操作。RGBAW合并五个 不同的二极管（红色、绿色、蓝色、琥珀色和白色）可以输出几乎任何颜色 通过混合这些二极管的输出来控制色轮。重要的是，RGBAW矩阵 不会影响定音鼓作为标准双色面板的性能。 但如果你有这么多的秘密，那又有什么乐趣呢？

全色矩阵实际上是5x5而不是4x5。第五列实际上是一个占位符，它没有任何作用。但是，第五行表示RGBA列的转换。有关更多详细信息，请参阅

What Is RGBAW? RGBAW refers to the design of the LED matrix that drives the Luxli lights, and it's what separates the Timpani from most other 1x1 lighting solutions. LED panels of yore usually had one of two different LED colors, either daylight balanced or tungsten balanced, or a combination of the two, for bicolor operation. RGBAW combines five different diodes (Red, Green, Blue, Amber, and White) to pump out nearly any hue on the color wheel by mixing the output of these diodes. Importantly, the RGBAW matrix doesn't take away from the Timpani's ability to operate as a standard bicolor panel. But what fun would that be when you have so much more under the hood?
