This application generates random numbers and creates hexadecimal codes for colors from them. It then shows the codes in corresponding colors. There is one button that opens a view which shows the random colors against a white background. Another button opens a view with a black background. There is still another button that opens a view that shows random colors in random backgrounds. Here, there are blocks each showing background and text colors. They are arranged in such pairs that the background color of one block is the font color of the other.
Finally, there is a view that shows some text in random colors and random font-sizes. The application also determines the font-sizes by using random numbers.
