Text colors and comprehension

Everybody will have a personal preference for the color of the text and background on their personal computers or cell phones. For a software or website developer, it may be impossible to choose a color combination that will be pleasing to all users. They have to think in terms of the preferences of most users.

Choosing the right color for text can be a very difficult and frustrating task. The text can be either pleasing to read or annoying to look at. Dark colored text with a light or bright background, is normally the most preferred choice. It must be ensured the there is enough contrast between the text and the color of the background.

Colors can also affect the readability of text. Poor readability will also cause difficulty in comprehension. It will slow down the reading process.
