[Outreachy Task Submission] Accessibility Issue with the 'Forgotten Password?' button in Login Screen

[Chiemezuo]

Intro

This is the second accessibility issue I found with the 'Forgotten Password?' button in the login screen. For the first, see #4757

Issue

Low contrast for the Forgot password? button and the login & signup when not in focus. This is a violation of WCAG Success Criterion 1.4.3 (Level AA) - Contrast (Minimum). See

Description

Success Criterion 1.4.3 (Level AA) - Contrast (Minimum) requires that the visual presentation of text and images of text must have a contrast ratio of at least 4.5:1, except for large text, images of text, and incidental text.

Impact

This means that some visually-impaired people will have trouble seeing the text at all, while some will have difficulty identifying it as a call-to-action.

Fix

Improve the contrast ratio to at least 4.5:1. This will require a design decision by the team, and involves testing with an automated tool.
