Beautifully colored but unreadable information is of no use to anyone. You must take special care when coloring text to maintain sufficient luminance contrast for legibility. If text is displayed on a background that varies in lightness or color (like all too many PowerPoint templates suggest), its prominence and legibility will shift with its placement. When coloring individual words for emphasis, be sure they are still readable—and never randomly color individual words or letters unless you intend to be confusing.
