Design with colour in an accessible way
Make sure that people with low or partial vision and/or colour vision deficiencies can perceive all web content that communicates information.
Information communicated through colour must also be made available in a way that does not use colour.
Any text or image of text needs to have sufficient contrast for sighted users to be able to read it.
Non-text content, such as graphical objects or active user interface components, needs to have sufficient contrast for sighted users to be able to see what it is and the meaning that it conveys.
