Colored tab chrome
Colored tab chrome is a feature simple to implement and can be made an option buried in some obscure area deep within the settings
Allow Orion's toolbar and tab bar to use the current websites accent color as the background color.

This should be an option users can enable as I know some do not like this.

The only thing I am really missing from Orion is Safari's implementation of the colored tab bar depending on a website's dominant colors when it is in its compact tab mode (which is another thing I would like to see but I heard that is being worked on).
iOS 15 and Big Sur added bar tinting to Safari, it would be neat if Orion did that as well:

Is it? Cause safari is doing that on mobile as well I think.
Never seen FF or Chrome do that tbh.
