While most general-purpose accessibility testing tools will notify you of problems with color contrast, and sometimes even suggest a better color combination, they can't catch everything. In some cases, you will have to find out what the relevant color values are and enter them in another tool to see if they meet contrast requirements.

Some tools will perform automated accessibility scans of entire site. Here are some good free ones.

Some software applications, either ones that must be installed separately or utilities that come with the operation system, can be used to test the accessibility of web pages.
