Named Colors within the Styles Page

[keithgrimes]

Is is possible to enter named colors into the Theme Styles pages instead of #nnnnnnn?

I appreciate there is a color picker but this does not provide names of colors e.g. Black, White or any that are in pre-defined variables within the stylesheet

Joomla 4.3.4
Gantry 5.5.16

Note using a custom theme based on g5_hydrogen.
