Test on Boost and Classic

Go to the login page

Open the browser's dev tools and inspect the colour of the normal texts (e.g. site title, Is this your first time here, remember username, etc.)

Confirm that their colour is set to "#212529"
Note: If its "color" CSS style is set to "inherit" you'll probably see the color in RGB, e.g. "rgb(33, 37, 41)"

Log in as a teacher in a course and go to the grade book.

Inspect the colour of the non-link texts within the table (e.g. the email addresses, grades).

Confirm that their colour is set to "#212529"

Open the Notifications popover.

Inspect the colour of the non-link texts within the popover.

Description

According to https://www.w3.org/TR/2008/NOTE-WCAG20-TECHS-20081211/G183, links and normal text should have at least a colour contrast ratio of 3:1.

From the WebAIM blog entry "WCAG 2.0 and Link Colors":

So if you combine these two requirements, in order to be Level AA conformant, your page must have all of the following:

A 4.5:1 contrast between the non-link text color and the background.
A 4.5:1 contrast between the link text color and the background.
A 3:1 contrast between the link text color and the surrounding non-link text color.

Currently, the normal text has a colour of "#373A3C" while links have a colour of "#1177D1" which results in a colour contrast ratio of 2.5:1.
