SHELL: Application menus have the wrong color

Tested on:

• ReactOS 0.4.12-dev (Build 20181231-0.4.12-dev-252-ga179012)
• Windows XP Pro SP2/3 x86

Expected result:

• Inactive application windows have greyed out menu text.
• Application menu background has RGB color [236, 233, 216] when using "Sky" scheme.

Current result:

• Inactive application windows have black menu text.
• Application menu background has RGB color [255, 255, 255] when using "Sky" scheme.

My suggestion for a fix:

• Take the color of "3D elements", calculate 2/3 of its brightness and apply to inactive window menus fe. [255, 255, 255] -> [170, 170 ,170] or [255, 127, 0] -> [170, 85, 0]. After doing so it will work exactly the same as checked with Windows XP.
• Change menu background color (Advanced... > Element: > Menu > 1st color) taken from XP style "Sky" from white to [236, 233, 216] as it should be.

It does not apply to ReactOS Explorer but other ReactOS applications
