[REQUEST] Add a basic `Color` object.

[i0bs]

Describe the feature.

People may want to be able to easily call upon colors. Since it should be at least an accepted concept, I am wanting to add a basic Color object that includes the official branding colors. Please note that other colors that are custom-defined are ideally frowned on for this idea since the core library is about making implementations strict to what Discord offer, which we can argue debatably with the branding colors.
