I know I do a lot of pieces in black-and-white.
Sometimes I even say to myself, “Seriously? Another black-and-white drawing?”
“Yes. Got a problem?”
There is something I really love about black-and-white. No matter how many color pieces I do, black-and-white is like that one boyfriend who you just keep going back to, not because he’s a sleazy hunk and a cheap date, but rather because he’s a romantic. He’s the boy next door who maybe everyone else failed to notice but you–and every time you come back, golly he just gets cuter.
In fact, a former professor was once singing the praises about the virtues of black-and-white art-making, saying that, “It’s really all you need. All of the visual information you ever need is there.”
I remembered this phrase, interestingly, on the heels of browsing one of my favorite textbooks by Martin Salisbury, where he states (and I paraphrase): “The important thing (about drawing) is whether or not the approach serves the drawing’s purpose.”
So. Let a drawing serve it’s purpose. i.e.: Show only what needs to be shown. Get rid of the weeds. Don’t overly complicate a piece if it shouldn’t be complicated, WHICH INCLUDES not adding color if it isn’t necessary.
I love black-and-white. So there!
