Describe the colour of a source.
We need a concept of colour more general than "g - r" in order to calculate e.g. atmospheric dispersion or a source's PSF

Equality comparison for colors.
Just a placeholder like everything else, but we explicitly let indeterminate colors compare as equal.
In the future, we'll probably want some way of doing fuzzy comparisons on colors, but then we'd have to define some kind of "color difference" matric, and it's not worthwhile doing that yet.
