This page may help you to create Power BI reports that follow accessibility standards.

2. Use descriptive, purposeful chart titles

3. Avoid using color as the only means of conveying information

4. Set tab order on all visuals on each page

5. Remove unnecessary jargon and acronyms from all charts

How to Check Color Contrast

1. Go to WebAIM. There are additional websites available for you to choose from, so feel free to use them if you're familiar with any other site
2. Input the colors. In this example, the font color is FFFFFF (white) and the background color is 83A99C (light green). The contrast ratio is 2.58:1, which is below the standard of 4.5. As a result, the test failed.
   
3. After changing the font color to 070707 (black), the test passed. The contrast is now sufficient.
