Quartz Light is an alternative theme for SAP Fiori applications. Color communicates importance and association, and provides direction to users. By applying the color palette, user interfaces guarantee a clean and lightweight design that is consistent and coherent across all SAP Fiori applications.

Color Balance

Color balance refers to the recommended mixture of light and dark, and colored and non-colored areas of any SAP Fiori app interface.

Approaching the ideal color balance for each page creates a visual rhythm throughout the application. It also helps to draw the user’s attention to the most important information and functions. Furthermore, it promotes a distinct and consistent look and feel throughout all SAP Fiori apps.

• The Quartz Light theme background colors are subtle, calm, reduced, and minimalistic.
• A reduced background color scheme ensures a stable base for any application content. Foreground colors support the importance, prominence, and visual connection of the information displayed.

Color Usage

Each theme is based on a set of individual base reference values. These are:

• Primary (main user interface colors)
• Secondary (accent colors)
• Grayscale (neutral values)
• Semantic (value state colors)

The reference colors listed on this page give a helpful indication as to where they are used in the UI controls and layouts. However, it is extremely important that reference values are not used directly in the control styling. The Quartz Light reference color values are specific to this particular theme, but are assigned to control parameters.

The reference colors are used as base values, which are then distributed into the UI controls via a stable set of theme control parameters that are available in each theme. Theme control parameters represent semantically named parts of the controls. They are decoupled from the actual color values so that the color values can be easily replaced. The theming guideline explains how these reference values are mapped to the user interface controls.

Primary Colors

The recommended primary colors leverage the uniqueness of SAP Fiori apps. The primary colors represent the overall look and feel.

SAP Fiori Launchpad Gradient

The gradient is mainly applied to launchpad or dashboard overview page types.

Accent Colors

Secondary colors can be applied to accentuate important elements. They make a vivid contribution to the overall UI and should be used sparingly.

Grayscale

Grayscale areas play an important role in any SAP Fiori user interface. They minimize the risk of over-stimulation and foster simplicity. White and the light grays are mainly used for areas in the background or for borders. Darker gray shades are primarily used for text.

Semantic Colors

Semantic colors can be used to represent a negative, critical, positive, neutral, or information status. For more information, see How To Use Semantic Colors / Industry-Specific Colors.

Indication Colors

The indication color palette is used to follow the color conventions in a line of business or industry. All values are themeable and the meaning of each color depends on the business context. For more information, see How To Use Semantic Colors / Industry-Specific Colors.

Accessibility

Color Contrast

Color usages for the Quartz Light theme within SAP UI controls are checked against the WCAG 2.1 accessibility requirements.

Controls and colors are carefully selected to fulfill the minimum contrast requirements. Contrast ratios vary for different controls due to variations in size, weight, fill, or structure.

The minimum contrast thresholds for the standard SAP Fiori theme are as follows:

• 4.5:1 for text and icons in normal size or smaller.
• 3.0:1 for text and icons in large size (and normal size bold).
• 3.0:1 for graphical objects (like charts) as well as visual details that identify a UI element and its state.

Goals of Good Color Contrast

The user must be able to see everything that is needed to understand and operate the screen.

• Texts are readable.
• Icons are recognizable and distinguishable (unless they are purely decorative).
• UI elements can be identified visually (not by trial and error).
• Active elements can be recognized as such.
• The focus indicator can be found quickly (on a 15″ monitor, a user with good vision should find it in less than a second from a distance of 2.5 meters).
• Emphasized and selected controls are recognizable.
• Scroll indicators are recognizable.
• Groups and other structure elements can be recognized.
• All other visual information can be recognized.

For the last two points, you can also use other options to make the visual elements easier to recognize, such as layout, spacing, or additional texts.
