During the accessibility audit #341 several issues were identified concerning poor color contrast: - [x] registration screen: text field label (light blue on white/black background) > !213 - [x] settings/change password screen: text field labels (light blue on white) > !213 - [x] settings screen: "change password" button (light blue on white/black) > !213 - [x] registration screen: "next" button (black text color on blue/gray (disabled) button) > already fixed on current `main` - [ ] registration screen: visual focus indicator on "show/hide password" button (light gray on white) - [x] registration screen: password strength indicator (light green on white / dark red on black) > !211 - [x] registration screen: form error color (red on black) > !202 - [x] message compose screen: send button (light green on white) > !212 these two issues were post-poned to #364: - registration screen: disabled "next" button if some of the fields are not properly filled (light gray on white/black) - settings/change password screen: disabled button (light gray on white) as well as: - add contact screen: close button (system-dependant window decoration, so I don't think we can/should do anything about it)
