When designing media to communicate information, such as charts, graphs, and slides, we often use a combination of colors. Typically, this involves a background and a foreground color. It’s important to ensure that the audience can easily differentiate between the two. One effective strategy is to maintain strong contrast between the background and foreground colors. For instance, using a light background with a dark foreground, or vice versa, makes it easier for the audience to distinguish between them. In contrast, using two dark colors or two light colors for both the background and foreground can reduce clarity and increase cognitive load, making it harder for the audience to process the information.
