Color loupe

A color loupe shows the output color that would otherwise be covered by a cursor, stylus, or finger during color selection.


Diagram showing the anatomy of the color loupe component. This component only contains a teardrop-shaped area to display color.


Example of a color loupe showing RGBa value (255, 0, 0, 0.34) on a color wheel, alongside the same value on a color area and a color slider.


The value represents the output color (with optional opacity) of one or more color input components (color area, color slider, or color wheel). This is what is being displayed inside the loupe.

Table of options#

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.

Usage guidelines#

Display combined values#

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:

  • 2 controls: HSL using color wheel (hue) and color area (saturation and lightness)
  • 3 controls: RGB using unique color sliders for Red, Green, and Blue
  • 4 controls: RGBa using unique color sliders for Red, Green, Blue, and Alpha
