<sp-color-field> component accepts color values in various formats: HEX, RGB, HSL, HSV, and shorthand HEX

HEX: A hexadecimal color is specified with: #RRGGBB. RR (red), GG (green) and BB (blue) are hexadecimal integers between 00 and FF specifying the intensity of the color.

<sp-color-field value="#ff0000"></sp-color-field>

Shorthand HEX: Shorthand hexadecimal color values are also supported. #RGB is a shorthand for #RRGGBB. In the shorthand form, R (red), G (green), and B (blue) are hexadecimal characters between 0 and F. Each character is repeated to create the full 6-digit color code. For example, #123 would expand to #112233.

<sp-color-field view-color value="#f00"></sp-color-field>

RGB: An RGB color value is specified with: rgb(red, green, blue). Each parameter defines the intensity of the color with a value between 0 and 255.

<sp-color-field view-color value="rgb(0,2555,0)"></sp-color-field>

RGBA: An RGBA color value is specified with: rgba(red, green, blue, alpha). The alpha parameter is a number between 0.0 (fully transparent) and 1.0 (fully opaque).

<sp-color-field view-color value="rgba(0,255,0,0.3)"></sp-color-field>

HSL: An HSL color value is specified with: hsl(hue, saturation, lightness). Hue is a degree on the color wheel from 0 to 360. 0 is red, 120 is green, and 240 is blue. Saturation and lightness are percentages.

<sp-color-field view-color value="hsl(234, 70%, 50%)"></sp-color-field>

HSV: An HSV color value is specified with: hsv(hue, saturation, value). Hue is a degree on the color wheel from 0 to 360. 0 is red, 120 is green, and 240 is blue. Saturation and value are percentages.

<sp-color-field view-color value="hsv(0, 70%, 50%)"></sp-color-field>

Events

The sp-color-field component fires a change event when the color value is changed. You can listen for this event to react to changes in the color value.
