\x escape sequences are GNU specific. Use the octal escape code instead.
filters/calendar is beyond help. It would need a complete rewrite to
make it work with POSIX awk.

When a signature contains a line that starts with an url, the url is not
highlighted properly:
--
Foobar
[38;2;255;255;175mmhttps://foobar.org
The trailing m of the signature color start \x1b[38;2;175;135;255m is
considered as part of the URL scheme (i.e. mhttps:// instead of
https://). Colorize the URLs first before wrapping with the signature
color.

Python is not available on all systems. Port the colorize filter to awk
as it is a more widespread POSIX utility.
Users are free to copy the filter into their home dir and tweak the
colors to their needs. The highlighted items are:
=============== ======= ======= ========= =================
Item Red Green Blue Color
=============== ======= ======= ========= =================
quoted text 1 95 175 255 Blue
quoted text 2 255 135 0 Orange

quoted text 4 255 95 215 Pink

This assumes a terminal emulator with true color support and with
a dark/black background.

This filter script is not compatible with the previous one. Rename it to
avoid issues with existing configs.
