Actual Results

The placeholder "User name, group or email" and "take a look at this page" text has an insufficient color contrast ratio with the background color. 

By Default:

Foreground: #7A869A

Background: #FAFBFC

Ratio: 3.6:1

On hover:

Foreground: #7A869A

Background: #EBECF0

Ratio: 3.1:1
 
The "Restrictions on this page may prevent people viewing or editing." text has an insufficient color contrast ratio with the background color. 

By Default:

Foreground: #808080

Background: #F5F5F5

Ratio: 3.6:1

As a result, low-vision and elderly users won't be able to identify the text. This will cause an unpleasant user experience for users.

Expected Results

Ensure all texts that appear have a colour contrast difference of at least 4:5:1 with the surroundings to ensure that users who cannot distinguish between the colours can still find the texts.

Increase the colour contrast of text to achieve a ratio of 4:5:1 which will help in fixing this issue.

Workaround

Currently, there is no known workaround for this behaviour.
