Color Formatting #

When using the color elements, use el.color to access the color property, which should manage itself in the color format supplied. If you supply a color in rgb() format, el.color should return the color in rgb() format, as well.

The current color formats supported are as follows:

  • Hex3, Hex4, Hex6, Hex8
  • HSV, HSVA
  • HSL, HSLA
  • RGB, RGBA
  • Strings (eg "red", "blue")

Please note for the following formats: HSV, HSVA, HSL, HSLA When using the HSL or HSV formats, and a color's value (in HSV) is set to 0, or its luminosity (in HSL) is set to 0 or 1, the hue and saturation values may not be preserved by the element's color property. This is detailed in the TinyColor documentation. Seperately, the element's value property is directly managed by the hue as represented in the interface.

Example #

<sp-color-wheel></sp-color-wheel>

Disabled #

A color wheel in a disabled state shows that an input exists, but is not available in that circumstance. This can be used to maintain layout continuity and communicate that the wheel may become available later.

<sp-color-wheel disabled></sp-color-wheel>
