This topic raises some important issues:
Black vs. white keys should be just visual/spatial reference
The very fact that some keys are white and others are black, despite having amusing historical background (see this and this -- spoiler: quora -- for further info), nowadays should be only useful for visual reference and self-localization on the keyboard. If you account just for the pitches, you will find out that every key has the same value, origin and destination, regardless of its color (I think the same applies to people, but it is another distant question). Therefore...
... you should really think of pitches and intervals
Really, learn how to build trichords, tetrachords and so on; learn how to measure the distance between notes and apply such knowledge to build common grounds for harmony under every tonal center. Dive into harmony, chord inversions and progressions, cadences and modulations; learn to play chords in open and closed forms; then you superimpose them and alter the bass notes; then you stack pitches in ways that were previously awkward, but will by then be product of a fine mixture of logic and feeling.
You will, sooner or later, realize that some "chords" (for lack of a better name) will eventually use one or many black keys; nonetheless, those "chord designs" should serve only as a reminder, an instant picture of the chord you already know. And there is an overwhelming plethora of chords (and non-chordal stacks of notes) that you should know. It will become much easier and more logical to think of every chord design as per its harmonic context and function, for its overall sonority (either unique or plain standard).
Learning the basics of music theory will allow you to know how to "use" them.
First, learn the name of the notes on the piano : http://teoria.com/tutorials/reading/index.php
Then, build scales : http://teoria.com/tutorials/scales/index.php
And lastly, create chords : http://teoria.com/tutorials/chords/index.php
Black keys are no different than white keys. They're just one semitone apart from the previous/next white key : the "space" between B and C is the same than between C and C# (in equal temperament, which is the temperament of most of the keyboards).
The black notes make up the pentatonic major scale of F#, and the pentatonic minor scale of Eb minor (or D#m). Playing tunes on them will sound good because the two notes that will clash from a major or minor scale have been removed.
Chords that can be played are - F#maj. D#/Eb min. F#sus2. C#sus2. C#sus4.
Maybe there are more, but that'll do for now. The problem as I see it is that there is very little to vary things and the sus chords can't resolve to their maj/min without using the white notes.Hope that helps, but what's the point ?
