Canvas@Illinois, Accessibility Checker Color Contrast

When using colored text, it's important to choose colors that maintain a high contrast with the page's background. Users with low vision or particular types of colorblindness may have trouble differentiating between similar colors, so the Accessibility Checker in Canvas will flag colored elements with low contrast ratios.

When a low contrast ratio is detected, the Accessibility Checker will display a description of the issue, a box to input a new RGBa color code, and a selection panel and sliders to choose a new color visually:

Once you've chosen a new color, click the Apply button to save the changes. The button will not be clickable if the new color is also at an unacceptable contrast ratio.
