Add different color schemes

There are only two color schemes right now. Add a few more and fix the binary color scheme selection logic.

Color schemes can be found here: https://coolors.co/palettes/popular

Start by locating the existing color scheme definitions and the binary color scheme selection logic in the JavaScript project. Review the palettes linked in the issue, then determine how many additional schemes are appropriate and verify that selecting either binary option produces the intended colors. Done means the new schemes are available and binary selection works correctly.
