Deep purple, and I have a few soft plastics in oil or something (black with colored sparkles) that I'll use in clear water. But largely most of my stick baits are white or holographic, I don't know if I've even considered using black.

I have caught all my lunker bass on a solid black worm. I never kept count, but while working for a fishing tackle company during the seventies and being FORCED to fish at least fifty percent of the time, I did catch more than my fair share of lunkers. I also painted the bottoms of my bass boats black. The tackle company that I worked for, Lew Childre and Sons, made all his rods in black and even made his first BB1 reels black and shipped them in a black cloth bag. Lew's old saying was that black makes green.

There is black, and then there is the professional, metallic looking black that commericial lures have. Most self painted lures come out dull like the one in the picture, and don't have the fish attracting appeal that the baked on finish of a commercially made lure has.

Caught my first bass 30 years ago on a Heddon Tiny Torpedo in black shore minnow, and still nail them to this day on that and the same color Baby Torpedo. I generally follow standard guidelines, using black in stained/muddy water and natural frog or white shore minnow in clear water, but honestly, I don't think color matters for a topwater much at all.

I don't use many black lures, but I do have a couple of real dark green colors, would that work the same?
