How the value get stored

Mode all

If the mode ist set to all (which is the default), the color picker don't store only the given value, it stores an array with following values:

  • hex: The color in hex format
  • oklch: The color in the OKLCH color space
  • coords: The values in the OKLCH color space. This is great for any color transformation. Very handy if you use something like the Tailwind OKLCH Plugin
  • customProperty: Ready to use custom properties for your CSS. You can set the name via the option customPropertyName, defaults to color
{
  "hex": "#65a30d",
  "oklch": "oklch(64.817% 0.17545 131.68)",
  "coords": {
    "l": 0.64817,
    "c": 0.17545,
    "h": 131.68
  },
  "customProperty": {
    "coords": "--color-l:0.64817;--color-c:0.17545;--color-h:131.68;",
    "oklch": "--color:oklch(64.817% 0.17545 131.68);",
    "hex": "--color:#65a30d;"
  }
}

Mode coords

If the mode ist set to coords, the color picker stores the coordinates of the OKLCH color as array:

{
  "l": 0.64817,
  "c": 0.17545,
  "h": 131.68393
}

Mode hex

If the mode ist set to hex, the color picker stores the hex color value: #65a30d

Mode oklch

If the mode ist set to oklch, the color picker stores the OKLCH color as string: oklch(64.817% 0.17545 131.68)

Settings

Add a property of type array and configure the editor as seen in this example:

Foo.Bar:Your.Prototype:
  properties:
    colorOKLCH:
      type: array
      ui:
        label: OKLCH Color
        inspector:
          editor: "Carbon.ColorPicker/OKLCH"
          group: yourGroupName

If you set mode to hex or oklch the type has to be string:

Foo.Bar:Your.Prototype:
  properties:
    colorOKLCH:
      type: string
      ui:
        label: OKLCH Color
        inspector:
          editor: "Carbon.ColorPicker/OKLCH"
          group: yourGroupName
          editorOptions:
            mode: oklch

Customization

The editor allows some global default options via your Settings.yaml file:

Neos:
  Neos:
    Ui:
      frontendConfiguration:
        Carbon.ColorPicker.OKLCH:
          # This option makes it possible hide the whole editor (incl. label) based on data source
          hidden: false
          # Set the mode of the color picker. Possible values are: 'oklch', 'hex', 'coords', 'all'
          mode: "all"
          # Disable the color picker
          disable: false
          # Allow empty values
          allowEmpty: true
          # Show preset selector
          showPresets: true
          # Show input field for hex input
          showHexInput: true
          # Show color picker
          showPicker: true
          # Show slider to set the lightness
          showLightness: false
          # Show slider to set the luminance
          showLuminance: false
          # Collapse the color picker (enables only when showPicker is true)
          collapsed: false
          # The name of the custom property. Only used when mode is set to 'all'
          customPropertyName: "color"
          # The precision of the OKLCH color picker. Set to 0 to disable rounding and use the raw values.
          precision: 5
          # Set the color contrast threshold for the color name output. Value between 0 and 1
          # Depend on the luminance, the text will be black or white
          contrastThreshold: 0.6
          # The presets are based on https://tailwindcss.com/docs/customizing-colors with the key 600
          # false and null values get filtered out. You can also disable all presets with presets: false
          presets:
            slate: "#475569"
            gray: "#4b5563"
            zinc: "#52525b"

        dataSourceIdentifier: "some-datasource"
        dataSourceUri: "some/custom-route"
        dataSourceAdditionalData:
          foo: "bar"
        dataSourceDisableCaching: false

The settings can also be set in your property configuration:

Foo.Bar:Your.Prototype:
  properties:
    colorOKLCH:
      type: array
      ui:
        label: OKLCH Color
        inspector:

          group: yourGroupName
          editorOptions:
            showLightness: true
            showLuminance: true
            disable: true
            allowEmpty: false
            collapsed: true
            customPropertyName: "color-main"
            contrastThreshold: "ClientEval: node.properties.contrastThresholdProperty / 100"
            presets:
              red: "#dc2626"
              orange: "#ea580c"

Eel helper

ColorConvert.toOkLch(color, precision, customPropertyName)

Converts a HEX color to the object who is used when you set the mode to all.

  • color (string|array, required) The color
  • precision (int) The precision for the color, defaults to 5
  • customPropertyName (string) The name for the ready to use custom property, defaults to 'color'

Example:

${ColorConvert.toOkLch('#65a30d', 4, 'color-main')}

returns

{
  "hex": "#65a30d",
  "oklch": "oklch(64.82% 0.1755 131.7)",
  "coords": {
    "l": 0.6482,
    "c": 0.1755,
    "h": 131.7
  },
  "customProperty": {
    "coords": "--color-main-l:0.6482;--color-main-c:0.1755;--color-main-h:131.7;",
    "oklch": "--color-main:oklch(64.82% 0.1755 131.7);",
    "hex": "--color-main:#65a30d;"
  }
}
