Turns out that osso-xterm which I based upon uses something a lot different
from apparently any other terminal -- they all use identical shades, much
brighter than what I copied:
Old: 00 2a 55 7f aa d4
New: 00 5f 87 af d7 ff
This did hardly matter as we immediately shoehorn the colors into only 16
values, but recently 24-bit codes turned from an oddity to something
widespread, thus it's better to handle 256 vs 24-bit consistently.
