Zorin Grey-Dark Accent Color

Hello Ladies and Gentlemen!

I have a Suggestion for a little Adjustment in the Zorin Grey Theme. In the Light Theme, You have a nice grey Accent Color. But when You switch to the Dark Theme, it changes to a black and white Sheme. I guess this is because of a better Contrast.

I would find it good when this will be changed to a Greytone, too. It don't have to be too dark. But I would like to have it in a more visible grey Color. Maybe with #808080 or similar.

It is not a big Thing what annoys me in a fundamental Way. It is only an Idea for Adjustment.

What I'd love to have is the option to add our own custom colors to the theme. This has been done here, so you can at least fix this yourself manually:
