Earlier today I hosted a webinar about tools that teachers can use to improve the accessibility of the slides, documents, and videos that they create for their students. In that webinar I shared a simple tool that is quite helpful when trying to determine what color combinations you should use on your slides or documents. That tool is the Accessible Color Matrix hosted on Github. As you can see my demo video, the Accessible Color Matrix provides a quick and easy way to see which color combinations do and don’t work from an accessibility standpoint.
