QB64 is open source and free. You can branch off from the repo and make yourself a custom QB64-Steves version, if you want. There's absolutely nothing wrong with adding, editing, or removing parts from the source for your own needs.
If you can completely take and modify all the rest of QB64, I can't possibly fathom any reason why you can't do the same with the color schemes.
If you're *really* paranoid about the issue, just change a single value by one point. Instead of comments being 255 red, 255 green, 84 blue, make the values 255, 255, 85. That's completely different! LOL!!
