            1) pick a color and reports it
            2) pass in a list of RGB(A) values each from 0-255 to create a color, where
                - a single item represents a gray scale
                - a pair of numbers represents a gray scale and an alpha value
                - a triple represents RGB

    * Please, oh please, use metaprogramming capabilities and variadic inputs wisely, if at all. They can be powerful abstractions, but there ain't not free lunch, they come with costs in expressivity and comprehensibility. Remember that naming things (and chosing distinct names) is a great strategy when communicating with fellow humans. It's sure nice to be revered by your peers for your inconceivable brilliance, but so much nicer to be understood. Never forget that among humans expressive is better than impressive, straight ist better than crooked, flat is better than nested, named is better than anonymous and explicit is better than implicit. Also remember that the one you're most likely talking to is your future you. Be nice to them!
