Color palette.

This provides the palette used for a theme.

The ideas packed in here are

• provide two colors for highlighting and accents.
• I always want some white, black and gray.
• I don’t want to miss out anything, so go once round the hue in HSV. Take steps of 30° then we hit pretty much anything interesting.
• Just one variant of each color is not enough, make it 4.
• Background colors need extra considerations. Extend to 8.
