Improve the color contrast for the menu item of the current page

Created on 13 February 2025, about 2 months ago

Problem/Motivation

The menu item for the current page is visually highlighted by a change in the background color and the menu item’s button label color. Problem is, most of the colors for menu item labels against the color of the background are not meeting the minimum requirement of 4.5:1 for SC1.4.3. Neither are most of the background colors meeting a minimum color contrast of 3:1 against the background of the navigation sidebar (See the table in https://docs.google.com/spreadsheets/d/1won35PxhRFexJYE8FmZ4DCNTo7xEAxC8... or current_page.xlsx.zip → for more details).

In Forced Colors mode the label for the active menu item is not visible at all.

Discussed and iterated on the issue with @mgifford, @the_g_bomb, @katannshaw, and @drupa11y

Steps to reproduce

Check the navigation sidebar after visiting admin/content/media or admin/structure/types. For testing the issue in Forced Colors mode make sure that you’ve switched to dark mode before.

Proposed resolution

Make sure that the color contrast between the menu item label and the background for the current page has at least 4.5:1
Increase the color contrast of the colorized background against the background of the navigation sidebar.
Make sure that the active menu item is also communicated in the Forced Colors mode

In this example, the "Extend" link is orange on a light orange background. This is lower contrast than the other links, making it harder to read for many people. It should be the opposite.

I have added a visible border to the active menu item in forced color mode. However, the task of increasing color contrast is still pending. As I’m currently occupied with other work, I’d appreciate it if someone could take it up. Thank you!
