4. "Interface Experience" is ... • Experience when using the interface

   • Interface Experience != User Experience

5. How does color affect people?

6. Color Psychology • Color psychology is the study of hues

   as a determinant of human behavior and feelings. • It is widely used in marketing ,branding and UI design, but is still in its developmental stages. • Feelings about color are often deeply personal and rooted in your own experience or culture.

   the color red before taking an exam actually hurt test performance. • Show more information: https://doi.apa.org/doiLanding? doi=10.1037%2F0096-3445.136.1.154 • We must choose the appropriate color for UI and product.

9. Accessibility: color contrast • “Success Criterion 1.4.3 Contrast (Minimum) (Level

   AA): The visual presentation of text and images of text has a contrast ratio of at least 4.5:1” (Web Content Accessibility Guidelines (WCAG) 2.1) • For more information: https://www.w3.org/WAI/WCAG21/Understanding/contrast- minimum.html

10. Accessibility isn't for the poor eyesight. • Device brightness and

    contrast settings • External environment for browsing contents(Sunlight, etc…) • It's important to use colors that are easy to read in any environment.

11. But… Accessible colors tend to be dark.
