Change the primary colors in manager template

[Ruslan-Aleev]

Feature request

Summary

After changing the logo, the old colors look out of place, especially green (since there is most of it in the admin panel).
I suggest changing them closer to the logo, for example:

Green (as from the logo, but darker):

Blue (as in the logo):

In the screenshots the color changed for red, and orange (as from the logo).

Why is it needed?

There is an unspoken rule in design: do not need to use many different colors (without connection to something), and in the template there is a lot of green and it is not associated with anything.

Personally, I don't like the colors suggested (agreed upon) with the logo.

I propose to prepare a palette of colors for buttons, switches, panels and their state on hover for the entire administrative panel. Since everything was done in haste.

And now some colors have problems with contrast and their accessibility.

For example:

That is, not all people are able to read the text without problems. We need to agree on everything.

I am against following every logo update and change the theme based on it. The new logo is just a marketing thing, which does not have to influence the user interface. Such changes make user guides with screenshots almost irrelevant.

I agree with @Ibochkarev and I would ask to create a new Proposal or feature about improvements with contrast and close it after.
