Steps to reproduce:

That's not a bug but a proposal improvement. i don't know the way to do.
Proposal:
After open inspector tool, in inspector css rule. When you have defined a color into a CSS custom properties. Add possibility to use color chooser.
Code :
-- Start code
:root {
    --nav_button_color: #337ab7;
    --background_color: #999999;
    --third_color: #337ab7;
    --news_background_color : #112233;
}
a {
    color: var(--third_color);
}
-- End Code
The goal is define all colors(or more importants) in CSS custom properties to change and test easy some colors combinaitions.
It's possible but should be easier with color chooser.



Expected results:

Appear colors chooser on CSS custom properties when find css colors defination like "#337ab7" and other.
