a. Colour Psychology in UI
When discussing UI design, colour psychology refers to the study of how colours influence people’s perceptions, feelings, and behaviour when using digital interfaces. It strongly influences users’ engagement, feelings, and ability to make decisions within an interface. It is essential in forming users’ experiences. UI design colour psychology in brief is summarised as follows:
Emotional Impact
Warm Colors (e.g., reds, oranges, yellows):
These hues frequently arouse feelings of energy, passion, warmth, and urgency. They can be used, for example, in sale announcements, to draw attention, generate excitement, or communicate a sense of urgency.
Cool Colors (e.g.,purples,greens,blues):
Cooler colors often convey sentiments of stability, calmness, and trust. They are frequently utilized in interfaces that call for a certain level of professionalism, peace, and trust.
Brand Identity and Recognition
Colours are important for both brand identity and recognition. Users are better able to associate specific colours with a particular brand when brand colours are used consistently throughout user interface elements.
Contrast and Hierarchy
You can use contrasting colors to highlight key components of the interface. For example, calls-to-action or important information can be highlighted by using vivid colors against a neutral background.
By drawing users’ attention to key components and fostering a sense of coherence, color hierarchy aids in the establishment of visual flow and organization within the interface.
Cultural and Contextual Considerations
Different cultural interpretations and meanings can be attributed to different colors. In some cultures, something that is viewed favorably may carry a different meaning. When selecting colors for a diverse audience, cultural context is an important factor to take into account.
Perception of color is also influenced by context. For example, the same color may have distinct connotations or feelings depending on the setting in which it is used, such as a gaming interface as opposed to a healthcare app.
Accessibility and Readability
Readability depends on text and background color contrast being sufficiently high, especially for users with vision impairments. A user-friendly experience depends on adherence to accessibility guidelines.
User Engagement and Decision-Making
Colours can be used strategically to affect user behaviour and judgment. For instance, a well-thought-out Colour scheme can motivate users to select items, click buttons, and browse the user interface.
