palette specifies the new values for the 256 palette colors: 8 standard colors, their 8 bright counterparts, 6x6x6 color
cube, and 24 grayscale colors.
Omitted entries will default to a hardcoded value.
palette.length must be 0, 8, 16, 232 or 256.
If foreground is null and palette.length is greater than 0, the new
foreground color is taken from palette[7]. If background is null and
palette.length is greater than 0, the new background color is taken from palette[0].
