This is years too late, but I'd still like to take this opportunity to
say a huge Thank You to Thomas for rescuing mintty from the ashes of
Google Code and maintaining and developing it so well since.

The rewrap on resize is another great and long-requested feature he's
added. It's on the Window page of the options for anyone who wants to
give it a try.

Re the colour themes, my original default has orderly colour values,
but rather uneven actual colours. For example, non-bold blue is barely
legible on a black background, and red is significantly darker than
green in diffs.

So I tried adjusting the colours to equal luminance according to the
formulas of the sRGB colour space, which resulted in the 'luminous'
theme. Unfortunately that has pretty much the opposite problem of the
original: e.g. red is too bright and yellow is too dark. And that's
because of this:

https://en.wikipedia.org/wiki/Helmholtz-Kohlrausch_effect

As I didn't find a suitable formula to compensate for that, I used
experimentally determined correction factors to get to roughly (and
subjectively) equal brightness, resulting in the 'kohlrausch' theme.

The 'helmholtz' theme that is now the default is identical to that,
except for a somewhat darker non-bold blue, as a compromise between
legibiility on black and use as a background colour itself in programs
like mc. The bold blue is similar to what's used for links on
dark-themed websites.

The original theme can be restored using the 'mintty' entry in the
dropdown on the 'Looks' page of the options. Existing colour
customisations should not be affected by the change of default.

Andy
