Color slider

A color slider allows users to visually change an individual channel of a color.

Anatomy#

Options#


Key example showing two color sliders, one in horizontal orientation, one in vertical orientation.

Orientation#

Color sliders can be either in horizontal or vertical orientation. By default, a color slider is horizontal and should be used when vertical space is more limited. The vertical orientation is used when horizontal space is more limited.

Key example showing three color sliders demonstrating use for selecting hue, color channel, and opacity.

Hue or opacity#

The color slider can be used to select hues, color channel values (such as RGB or CMYK levels), or opacity.

Behaviors#


Flexible length#

While the color slider has a fixed thickness (24 px on desktop, 30 px on mobile), the length of the color slider is flexible and can be customized to appropriately fit its context. The minimum length is 80 px on desktop scale and 100 px on mobile scale.

Key example showing horizontal color slider length annotated with customizable length.

Handle behavior#

Unlike the slider itself, the color slider’s handle can slide all the way to the edge of the track. It always displays the selected color inside the handle and never gets cut off by the track or any container.

Key example showing three horizontal sliders with the handle either at the first or last position, with the slider demonstrating color hue, channel, or transparency.

Loupe behavior (down state, finger input)#

On down (touch), a loupe appears above the handle to show the selected color that would otherwise be covered by the finger. This only appears on finger input, not mouse or stylus. It appears 10 px above the edge of the handle on desktop scale and 8 px on mobile scale.

Key example of a color slider demonstrating the loupe relative to the handle and finger position.

Usage guidelines#


Include labels#

Color sliders should be labeled and, when applicable, be accompanied by text fields. In a context when labeling each individual slider may be redundant, make sure to still label the group of sliders (“RGB,” “HSB,” etc.)

Display color selection#

When using color areas, it’s important to clearly display the color selection in real-time. It can be in a color swatch, or directly on the canvas, or both.

Key example of a color swatch above three color sliders being used to select values for red, green, and blue color channels and one color slider for transparency.

Keyboard interactions#
