At night All Cats Are Gray

On a weeknight, after work, I sat at the kitchen table to draw a Doodle. I knew my choice of colors was limited as I was waiting for ink refills for my markers. I had some pale beiges or grays that still worked well. I started my scribbling as usual, not too confident that I could find something that would look good with only those colours. And what popped out of the drawing? A little cat. PERFECT! Isn't there a saying that at night, all cats are gray?
