No, not enough. Never enough.
I work with color in my spare time, i.e., while riding public transportation. I find it endlessly fascinating. It speaks to me, not in any organized way, but nonetheless.
Sometimes I make mistakes, even, particularly when working in light that is not sunlight. It is easy to mistake colors as it is easy to mishear tones.
On one of my cd's I end a piece in the wrong key. It is a contemporary piece, so nobody notices. The sound of the piece led me to this wrong key. The composer in question, Bartok, loved to play with that sort of sound/wit.
Note: The composition in question is available on my Haydn/Bartok CD.
