Details

Currently, ANSI_COLOR in /etc/os-release is set to:

$ grep ^ANSI_COLOR /etc/os-release
ANSI_COLOR="0;36"

This is blue, according to the terminal emulator's palette. However, with my very scientific method of downloading the artwork PNGs and using a color picker. Our actual color is something completely different.

Hence we should use an ANSI color sequence here that matches this color precisely, by specifying the correct R/G/B parameters. i.e.

ANSI_COLOR="38;2;23;147;209m"


To see the difference between this precise 24bit specification of blue and the paletted blue of your terminal emulator, type:

echo -e '\e[38;2;23;147;209mArch Linux blue\e[0m vs. \e[0;36mplain blue\e[0m'

The difference in color varies from terminal emulator to terminal emulator.

(All relevant terminal emulators understand these sequences since a long time, including the Linux kernel)

This bug is very very important, and shamelessly copied from https://bugzilla.redhat.com/show_bug.cgi?id=1823099. Clearly and obviously.
This task depends upon

I can't edit. But the correct ANSI_COLOR is

ANSI_COLOR="38;2;23;147;209m"

Very important, obviously!

I checked into https://www.archlinux.org/static/logos/archlinux-logo-dark-scalable.518881f04ca9.svg code, the color is well #1793d1, so (R,G,B) = (23,147,209).

I'll update this variable to:
ANSI_COLOR="38;2;23;147;209"

Note: the final m was dropped from your proposal.
