That's as good as it's going to get with a 3-bit display, meaning you have only 8 colours to work with. Any other colours are created by dithering. You can see an example of the palette here:

I think it looks great though.
Edit: the wave clock is just using the available colours properly, which prevents dithering from occurring.
