It will be easier for the user to read text if the text itself is not moving or flashing. Color and contrast Color and contrast are also great attention grabbers. Foreground colors should be hotter and lighter because this is where you usually want to focus the user's attention. Background colors should be cooler and darker so they do not draw attention away from the main subject matter. Remember, too many colors can become distracting, so use them conservatively.
Readability Use a mixture of upper and lower case letters, rather than all capital letters.
This will increase the readability of your text. To maintain that readability, it is best to use only two type styles on any one screen. Although many software tools offer dozens of type styles and sizes, more than two is usually confusing. If you want more variety, consider using different sizes and weights for each of your type choices.
