However, in general, converting between two non-absolute color spaces (for example, RGB to CMYK) or between absolute and non-absolute color spaces (for example, RGB to L*a*b*) is almost a meaningless concept.
然而，通常两个非绝对色彩空间之间的转换（如RGB到CMYK）或者绝对色彩空间与非绝对色彩空间之间的转换（如RGB到L*a*b*）尽管也可以用公式得到大致相等的结果，但其实概念上是没什么意义的。
