A good color mastery in Interface Design (UI) is crucial. It can improve usability and also help to influence the perceptions a user may have, like strengthening brand recognition and generating more conversion.
Color is one of the most powerful tools in a designer's arsenal. Finding a killer color combination can create harmony and level up the overall experience considerably.
Color contrast gives dynamism to the interface. You can create high contrast by using complementary colors. These are colors that face each other in the color wheel.
The characteristics of interaction elements, for instance, the color, must be used consistently throughout the interface. For example, calls to action need enough contrast so that the user can identify them quickly.
