No. In fact, some have no color at all and have to be analyzed with a UV light to even see. For TLC, you can compare the distances travelled against known standards.
In column type chromatography such as HPLC, the color is irrelevant - the times at which different substances come off is more important. You can compare the time it takes standards to come through to see what your sample is composed of.

No, other compounds will separate, but you won't see them. The color isn't what makes them separate, but rather they separate according to charge, weight, solubility, ...

Are you sure you are not confusing this with colorimetry? Even then - it does not "separate" compounds - simply helps identify strength/concentration.
