There are different ways to make a web page more easy to read, but there are two options that come directly from the operating system that many developers and designers seem to confuse — high contrast and inverted colors.
While the confusion may not be a big deal in most contexts, when talking about implementing support for each it can be critical to know which one you are targeting. Those of who practice the dark arts of accessibility want to be as precise as possible when testing and implementing.
This post is not a judgment about either approach. They both are useful for users in different contexts and do what each says on the tin.
