Intro

Color sets the visual balance of SAP Fiori for Android apps. On screen, color is used to define the visual hierarchy of UI elements and to direct the user’s attention to complete their tasks.

Horizon Theme Color Palette

The Horizon color palette introduces a unified color palette that brings our brand and products together to achieve a cohesive experience across all SAP touchpoints. The Horizon color palette is designed to provide bold and vibrant color while remaining accessible in instances with complex UIs.

UI Colors

UI colors are colors that are grouped based on their role or usage within the UI. This additional level of abstraction allows product teams to swap out the default Horizon theme with their own product colors. UI colors are grouped into the following color groups:

  • Surface colors
  • Text colors
  • Borders colors
  • Semantic colors
  • Accent colors


Surface Colors

Surface colors are colors applied to the background of all components. These colors contrast with all foreground colors and are the basis for the overall theme. Surface colors are identified by the letter S followed by a number sequence (e.g., S1, S2, S3) in our UI Kit.

Border Colors

Border colors are applied to any linear elements such as dividers or graphical elements used to define any areas within components. These colors range from neutral grey colors to interactive brand colors often used to communicate the state of a certain part of a component. Border colors are identified by the letter B followed by a number sequence (e.g., B1, B2, B3).

Semantic Colors

Semantic colors are applied to any foreground or background elements such as text, icons, or backgrounds to communicate a component’s status, state, or level of priority. These colors are bright in hue to direct the user’s attention to a certain component or part of the UI. Semantic colors are identified by the following naming (e.g., negative label, critical label, positive label, and neutral label).

Accent Colors

Accent colors provide an additional level of color luminance and are used to accent areas of the UI such as avatars, icons, and decorative areas. These colors are bright in hue and provide visual variety to the UI. Accent colors are identified by the word “Accent” followed by a number sequence (e.g., Accent 1, Accent 2, Accent 3).

Accessibility

The Horizon theme color palette offers color mapping logic that is easy to understand. It introduces eleven tonal values across nine color hues of vibrant and bold color. Our Horizon theme color palette ensures that color combinations comply with WCAG accessibility standards.

Elevation

Elevation plays a key role in the Horizon theme color palette. In light mode, the drop shadow represents the elevation of the components. However, in dark mode, elevated components are differentiated by changes in tone to mimic a range of depth. At lower elevations, the surface tone is darker, while at higher elevations the tone is lighter. Refer to the following table to understand elevation.

Themes

The Android design system includes systemwide appearance settings for light and dark modes which use color consistently and sparingly.


Light Mode

Light mode is the default mode for the Android design system. Light mode is a bright UI that displays dark grey foreground elements and saturated accent colors against light surfaces. In light mode, neutral colors are used to make content readable, and accent colors are used sparingly to call attention to important information or show the relationship between parts of the interface. Lastly, light mode is best used in bright environments where battery life isn’t an issue.

Dark Mode

Dark mode is the secondary mode for the Android design system. Dark mode is a dim UI that displays white foreground elements and desaturated accent colors against dark surfaces. In dark mode, all component surfaces and backgrounds are dark grey in color with tonal variations depending on a component’s elevation. Lastly, dark mode preserves battery life (especially on OLED screens) by reducing the usage of light pixels, helpful in scenarios where the user needs to reduce battery consumption.
