Gnome Shell version: 3.22.1
Remark for White Theme
While using the White Theme I noticed that white background against grey sections and a light font make for a dull visual experience. in short, I think the shades chosen can be improved.
Remark for Global Dark Theme swithced ON
The light font against a dark grey background is both hard to see as well as mismatching.
Squashed Menus
Albeit sectioned, menu is sandwiched.
In Dark theme, too.
Lack of space
Programming Mode is too near the radio button.
Glow too pronounced
Too white-ish and area of glow is large.
Radio Buttons
In Dark theme radio buttons are pixelated, so-to-speak.
Font Colors, Lines & Bars
Font-color of title bar is too light against the white background. Compare with menu font-color.
Font-color against orange background. Suggest black font.
Fonts of both titlebar and window and progress indicator colour. Suggest a darker shade of grey (lol)
Font against blue highlighting background. Suggest darker shade.
Look for mouse pointer. Note white font against grey background and two blue lines above and below button.
Light font against blue background.
A light font against dark grey do not seem to match. Also, hard to see in terms of coloration.
Terminal
White Theme
Dark Theme
Correct me if I'm wrong but I think the terminal is governed by the shell. i.e. all good here!
