Colors and the UI
As the name suggests, GUIs (Graphical User Interfaces) present their features and functions visually. The human-computer interaction is heavily based on seeing things, looking for things and interacting with graphical UI elements. Color is a main characteristic of any visual scene, not only on computer screens, but in any situation where we see something. Because most of what we see and interact with in our everyday life is colored (as opposed to shades of white-gray-black), we are very familiar with colors – maybe so much that we don’t think about them a lot. On the other hand, it does bother us when we need to read a dark-gray label on a black button. So colors have the potential to boost or wreck the user experience. This article will introduce the concept of user experience and highlight some aspects of colors and color perception together with recommendations for UI design.
