Y′ values are conventionally shifted and scaled to the range [16, 235] (referred to as studio swing or "TV levels") rather than using the full range of [0, 255] (referred to as full swing or "PC levels"). This practice was standardized in SMPTE-125M in order to accommodate signal...

有多种方法可以在代码中定义颜色。最常用的方法是指定三种基色的值 - 红色、绿色和蓝色 (RGB)。本文通过指定色调、饱和度和亮度 (HSB) 的值来探索替代机制的使用。可以以更直观的方式使用 HSB 属性来创建颜色搭配良好的调色板。 网上有很多关于颜色的资源,我发现 Jonathan 的Learn about Hue, Saturation and Brigh...
另外在英文里的”white water”指清澈的流水,”white room”指手术室,”white coffee”是指加糖的或者加牛奶的咖啡”,等等。又比如,”white”还表示书面的、书面形式的,也中性词代表之一,例句”She gave me assurance in black and white”,译为她给了我书面保证。由此看出颜色词“白”,在中文中代表恐怖和死亡...
Each component can take any value between 0 (black) and 1 (white). For example, if each component takes a value between 0 and 1, the total range of possible colors is 0 to 255. When these three numbers are added together, the resulting number represents the light's intensity. ...
