http://en.wikipedia.org/wiki/Lab_color_space
这是维基上Lab表示法的页面
最後一段它说:
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
它说明了几种常见的RGB color space
以及
http://en.wikipedia.org/wiki/Color_space 它说明了何谓color space
你给的网站上面有对是否为sRGB分开转换 原因在此
