Make background color neutral gray [Feature Request]

[hyuri]

Hello!

Suggestion

I would like to make the suggestion of removing the green tint from the background, and making the background pure gray, preferably 18% gray (also known as "middle gray": https://en.wikipedia.org/wiki/Middle_gray).

The Reasoning

The green tint in the background makes the app look very cool, but that color tint interferes with our perception of the colors in the palette. I've studied color theory and worked as a colorist in video production, and the colors surrounding the colors we're working with affect our perception of those colors.

More + Examples

Colors can be perceived darker, brighter, or even a different hue or saturation depending on the colors surrounding them. We can see those effects with optical illusions like the following ones showing the effect on brightness, where grays are exactly the same shade but other elements around them make them appear different shades:

(Block the highlight and shadow bevel in the middle, and the colors around the gray blocks to see the effect)

Thanks!

The tint shouldn't reach the part of the window that is showing colors, but I can reduce the strength.

Any chance we can get an option of getting the default libadwaita background? I'd really love to see this app look consistent with other apps
