Updates to the default admin color scheme

Over on Makemake A collection of P2 blogs at make.wordpress.org, which are the home to a number of contributor groups, including core development (make/core, formerly "wpdevel"), the UI working group (make/ui), translators (make/polyglots), the theme reviewers (make/themes), resources for plugin authors (make/plugins), and the accessibility working group (make/accessibility)./Design, @hugobaeta has posted about some subtle updates to the blues and grays of the default admin color scheme. Work on updating the adminadmin (and super admin) has been completed in #31234. For those who are using those colors in their development, particularly any large areas of colors such as backgrounds, you may want to take a moment to update those values. There’s a handy guide to the changes on the post.

While we haven’t yet settled on a sensible and semantic way to provide helpers or utilities for these kinds of CSSCSS Cascading Style Sheets. changes, thoughts and eyes are welcome on #26691 for that.
