The energy state of these electrons is very low, meaning that the will not easily be agitated by photons to give off color. If you look at colored compounds, they tend to be mostly compounds containing transition metals. That is because these transition metals can hold many electrons loosely bound to them, which can move up and down in energy and give off color when struck by photons.

The number of electrons has nothing to do with colour. Whether they absorb or reflect certain wavelengths of light determines colour. In the case of CO, they don't absorb any particular wavelengths unless ionized in a gas spectrum tube.

it is not coloured because it does not absorb or reflect light.
it does not have anything to do with any odd e-
