http://en.wikipedia.org/wiki/Lab_color_space
這是維基上Lab表示法的頁面
最後一段它說:
Programmers and others often seek a formula for conversion between RGB or
CMYK values and L*a*b*, not understanding that RGB and CMYK are not
absolute color spaces and so have no precise relation to an absolute color
space such as L*a*b*. To convert between RGB and L*a*b*, for example, it is
necessary to determine or assume an absolute color space for the RGB data,
such as sRGB or Adobe RGB.
另外可以看http://en.wikipedia.org/wiki/RGB_color_space
它說明了幾種常見的RGB color space
以及http://en.wikipedia.org/wiki/Color_space 它說明了何謂color space
你給的網站上面有對是否為sRGB分開轉換 原因在此
