New edX color palette contrast ratio test

Color contrast is only an issue for text and icons. The colors that fail below can be used in visual content that is not text or icons. All color tests below are performed on a white and black background. They are likely to fail on anything but white or black. Once a palette is agreed upon we should conduct another set of tests to establish acceptable background colors that these can be used on.
