Colors
Colors play an important role in text readability, element identification and interactions. They are also responsible for making a connection with our brand.
Text readability
All interface texts must meet minimum contrast criteria. WCAG requires an AA level of contrast, equivalent to 4.5:1 between regular and background text, and 3:1 for larger text.
Primary colors
The primary colors are the colors that predominate in the elements, bringing greater prominence on the screens.
