Color Gradients not applied in TouchBar Buttons

[smileBeda]

When you create a TouchBar Button and set a Color that has a transparency factor, that transparency is never applied.

For example, create a TouchBar Button and give it "blue" apple color like in the screenshot, apply transparency.

That Blue will be the exact same as if you apply no transparency.
It seems to be the same problem with all colour types

I am on the latest stable release 3.108

Any ideas on how to solve this?

This is also still happening.
I just tested other system colors and some of them do not seem to "work", means they simply don't apply:
labelColor, primary to quaternary.

Just a design issue.
