Text with low contrast can be difficult to read for people with low vision. There are web sites that have, for example, poor color combinations such as blue links on black backgrounds. They aren’t easy to read even for people with unimpaired vision and can be virtually impossible for people with vision disabilities. Strongly contrasting colors can make it quicker and easier to read from your PC.
High contrast themes use more distinct colors to make text and apps easier to see.
