Success Criterion 1.4.1 Use of Color Understanding Use of Color | How to Meet Use of Color (Level A) Color is not used as the only visual means of conveying information, indicating an
      action, prompting a response, or distinguishing a visual element. Note This success criterion addresses color perception specifically. Other forms of perception are covered in Guideline 1.3 including programmatic access to color and other visual presentation coding. Success Criterion 1.4.2 Audio Control Understanding Audio Control | How to Meet Audio Control (Level A) If any audio on a Web page plays automatically for more than 3 seconds, either a mechanism is available to pause or stop the audio, or a mechanism is available to control audio
      volume independently from the overall system volume level. Note Since any content that does not meet this success criterion can interfere with a user's
      ability to use the whole page, all content on the Web page (whether or not it is used
      to meet other success criteria) must meet this success criterion.
