A color loupe shows the output color that would otherwise be covered by a cursor, stylus, or finger during color selection.
From the design point of view, each component has a number of options. These options and their names are platform agnostic, and each implementation should adapt these to fit into their framework.
color (with optional opacity)
Color selection usually happens using a variety of input methods (color area, color slider, color wheel). The color loupe should display the final output color: the combined values from multiple color inputs.
The number of input methods is determined by the color space (or “mode”), for example:
|May 13, 2020||1.0.0|
Includes all interactive states that are applicable (hover, down, focus, keyboard focus, disabled).
Works properly across all four color themes (lightest, light, dark, darkest).
Includes a desktop scale (UWP, macOS, web desktop) and a mobile scale (iOS, Android, web mobile).
Color is not used as the only visual means of conveying information (WCAG 2.0 1.4.1).
Text has a contrast ratio of at least 4.5:1 for small text and at least 3:1 for large text (WCAG 2.0 1.4.3).
Visual information required to identify components and states (except inactive components) has a contrast ratio of at least 3:1 (WCAG 2.1 1.4.11).
UI language and information design considerations have been incorporated into component design.
Includes relevant options (variant, style, size, orientation, optional iconography, decorations, selection, error state, etc.)
Includes guidelines for keyboard focus, layout (wrapping, truncation, overflow), animation, interactions, etc.
Includes a list of dos and don'ts that highlight best practices and common mistakes.
Includes content standards or usage guidelines for how to write or format in-product content for the component.
Works properly across various locales and includes guidelines for bi-directionality (RTL).
Follows WCAG 2.0 standards for keyboard accessibility guidelines and includes a description of the keyboard interactions.
All design attributes (color, typography, layout, animation, etc.) are available as design tokens.
Includes a downloadable XD file that shows multiple options, states, color themes, and platform scales.
Includes a downloadable XD file, generated by code using design tokens defined in Spectrum DNA, and shows multiple options, states, color themes, and platform scales.
Component is included in the Spectrum for Adobe XD plugin.
