About the Predefined Base Themes

The predefined base themes, SAS Light and SAS Dark, override the Flex standard (Halo theme) styles. The SAS Light and SAS Dark themes are implemented in a minimal way, without custom graphical skins. The SAS Light theme uses shades of light gray, beige, and white for its color palette. It should be used if a company’s theme contains an overall, light palette. The SAS Dark theme is based on darker, charcoal gray tones and should be used if a company’s theme contains a dark palette.
The SAS High Contrast theme improves the accessibility of the text and interface for visually impaired users. The SAS High Contrast theme uses a black background, with white outlines, text, and icons. A currently selected (active) item is aqua color and previously selected items are purple.
When you choose a base theme, select the theme that is most similar to your desired color palette.
