{% macro random_name() %}
{#-
This will return one of the official color names recognized by Home Assistant
lifted directly from the Home Assistant core github November, 2023 at
https://github.com/home-assistant/core/blob/dev/homeassistant/util/color.py
and the Official CSS3 colors from w3.org:
https://www.w3.org/TR/2010/PR-css3-color-20101028/#html4
Names do not have spaces in them so that we can compare against
requests more easily (by removing spaces from the requests as well).
This lets "dark seagreen" and "dark sea green" both match the same
color "darkseagreen".

Names must not have spaces, uppercase, or punctuation in them so that we can
compare against requests more easily .
This lets "dark seagreen" and "dark sea green" both match the same
color "darkseagreen".
If the exact name is not found, it will return "0.0.0", IE black,
because then name you provided is not a color on the official list.

For default the color is set to black [0,0,0] and the range is 0, so it will
by give you black for invalid input.

Names do not have spaces in them so that we can compare against
requests more easily (by removing spaces from the requests as well).
This lets "dark seagreen" and "dark sea green" both match the same
color "darkseagreen".
You also get the RGB color code for each of the color names.
SAMPLE USAGE:
{% from 'color_multi_tool.jinja' import color_list %}
{{- color_list().split('\n') | list -}}
