What goes into a matrix color space? The ubiquitous sRGB color space will serve as our specimen color space. Pictures are used to illustrate xyY space, chromaticity coordinates, D# white points, and the meaning of

Also found in: Wikipedia. Adobe RGBA color space defined by Adobe in 1998 that enables images edited in RGB to translate accurately to most color printers (CMYK printers). The Adobe RGB color model has a much greater color gamut than sRGB and Apple RGB, but not as large as CIE Lab. ...
图片来自https://en.wikipedia.org/wiki/CIE_1931_color_space 有了xy色度图,就可以通过xy的值找到对应的颜色。注意xy色度图只有色度信息,没有亮度信息,但我们前面说过,XYZ三刺激值中的Y就表示亮度。x,y,Y完整表示了一个测试光的色度和亮度,因此xy色度图也称为xyY色度图。 X和Z刺激值可以从x和y与Y计算回来...
RGB refers to an additive color model made up of Red, Green, and Blue light. Each channel of component color combines with the other two to to form a range of unique colors. In an RGBA color space, an additional Alpha channel can be assigned to define op
I would suggest you actually study up on this stuff on Wikipedia and other sites that explain things like XYZ Color space and the sub-sets such as RGB, CIELab and how it translates to physical reproduction processes such as CMYK printing. Similarly, there are enough articles out there that ...
本文主要介绍Color Model。Color Space常常涉及到许多具体的数学操作。两者在概念上有时候也会混淆一谈,倒也无所谓,基本上只有行业内人士才需要严格区分概念。 B: 常用的Color Model简介: http://en.wikipedia.org/wiki/Color_models RGB在计算机显示中广泛采用(比如LCD,LED),其原色(Primary color)为RGB,是一种加...

色彩空间一词源于英文的“Color Space”,色彩学中,人们建立了多种色彩模型,以一维、二维、三维甚至四维空间坐标来表示某一色彩,这种用坐标系统来定义的色彩范围即色彩空间。 例如计算机监视器上显示颜色的时候,通常使用 RGB(红色、绿色、蓝色)色彩空间定义,红色、绿色、蓝色被当作 X、Y 和 Z坐标轴。另外一个生成同...
