Workover the local variable colorization mechanism. The colors are now picked automatically from the color wheel, and the user will be able to tune with the following tunables:
- Count of generated colors
- How much they should be mixed with the standard text foreground color(to increase contrast, reducing distinguishability)
- An offset in the color wheel to manipulate the picked colors

The immediately visible effect is that the colors have more contrast to the background, reducing the "crazy-driving" effect.
