System Information
Operating system: Windows 10
Graphics card: 1080, 1070

Blender Version
Broken: blender-3.0.0-beta+v30.11392829adfe
Worked: 2.93

Short description of error
I really like my header to be completely transparent so that I can only see buttons on top of my viewport, freeing some more space in vertical area to preview more space on the scene I am working. I thought in all previous 2.8 and 2.9 iterations it was ruled out that free vertical space in viewport is more important as we use widescreen monitors. Now when I change my alpha to 0 in header option in 3d viewport theme preferences header is not becoming completely transparent, but at the same time for some reason I can still change it's color. That feels weird and inconsistent and a bit claustrophobic, I hope this trend of minimizing view-port area by default will not continue.

Here's a screenshot how it looks now in 3.0:

Changing Alpha value doesn't affect transparency of the header, but you can change color:

Here's a screenshot how it's "supposed" to look and it looks in 2.93:

Exact steps for others to reproduce the error

Go to preferences
Theme space
3d viewport
Open Theme Space tab
Try changing alpha and color values:

I can confirm. The alpha value only affects the second of the 2 bars. With the switching of the Tool Settings and Headers in #91536 (Swap Tool Settings and Headers in Editors), that makes the alpha only affect the Tool Settings. It seems really odd that the RGB color values affect both bars, but the alpha only one. IMO it seems like each bar should have separate color and opacity settings.

2.93

3.1

According to @fsiddi (see: {https://developer.blender.org/T91536#1226959}),

when it comes to header transparency, let's keep it as it is an deal with it in a separate revision. I agree it's not essential right now, and we should provide a clear mockup for it

It seems like adding a separate transparency control is planned, but there is no current revision posted that I can find.
I'll set this as confirmed for now.

From what I can remember this broke when the Active Viewport Colors were inverted. Header becomes lighter when mouse over. This looks really awful and has been an issue for a while.
