No, a compound doesn't need to be colored to be separated by chromatography. There are plenty of detectors that can be used outside of the visible spectrum, and in fact don't even use spectroscopic methods, such as Electron Capture detection (ECD).

No. They need not be colored in order to be separated. If they are colored, it makes them easier to see once they are separated, but even if not colored, you can visualize the separated compounds by other means.
