buttonImage ('images/ui-colorpicker.png')

Same as jQueryUI DatePicker.

buttonImageOnly (false)

Same as jQueryUI DatePicker.

buttonText (null)

Same as jQueryUI DatePicker. If null, use language default.

closeOnEscape (true)

Close the window when pressing the Escape key on the keyboard.

closeOnOutside (true)

Close the window when clicking outside the colorpicker display.

color ('#00FF00')

Initial color. Formats recognized are:

• #rrggbb
• rrggbb (same as previous, but without the #)
• rgb(rrr,ggg,bbb)
• rgba(rrr,ggg,bbb,a.a)
• rgb(rrr%,ggg%,bbb%)
• rgba(rrr%,ggg%,bbb%,aaa%)
• w3c-defined color name

colorFormat ('HEX')

Specifies the format of the color string returned in callbacks. You can either specify one of the predefined formats:

• #HEX #112233
• #HEX3 #123 if possible, otherwise false.
• HEX 112233
• HEX3 123 if possible, otherwise false.
• RGB rgb(123,45,67) if opaque, otherwise false.
• RGBA rgba(123,45,67,0.123%)
• RGB% rgb(12%,34%,56%) if opaque, otherwise false.
• RGBA% rgba(12%,34%,56%,0.123%)
• HSL hsl(123,45,67) if opaque, otherwise false.
• HSLA hsla(123,45,67,0.123%)
• HSL% hsl(12%,34%,56%) if opaque, otherwise false.
• HSLA% hsla(12%,34%,56%,0.123%)
• NAME Closest color name
• EXACT Exact name if possible, otherwise false. or specify your own format... Each color channel is specified as a pair of two characters. The first character determines the color channel:
• a Alpha
• r, g, b RGB color space; red, green and blue
• h, s, v HSV color space; hue, saturation and value
• c, m, y, k CMYK color space; cyan, magenta, yellow and black
• L, A, B LAB color space; Luminosity, *A and *B. The second character specifies the data type:
• x Two-digit hexadecimal notation.
• d Decimal (0-255) notation.
• f Floating point (0-1) notation, not rounded.
• p Percentage (0-100) notation, not rounded. If you prefix a valid pair with a backslash, it won't be replaced. All patterns are case sensitive. For example, to create the common hex color format, use "#rxgxbx". For an rgba() format, use "rgba(rd,gd,bd,af)"

You can also specify an array of formats where the first non-FALSE one is returned. Note that the only formats able to return FALSE are the predefined formats HEX3 and EXACT. For example, this array will output HEX3 format if possible or HEX format otherwise:

• ['HEX3', 'HEX']

dragggable (true)

Make the dialog draggable if the header is visible and the dialog is not inline.

duration ('fast')

Same as jQueryUI DatePicker.

hsv (true)

Whether or not to show the inputs for HSV.

inline (true)

If set to false, attaching to a non-input will still make the dialog a popup instead of inline. Make sure you handle events to catch the color change, otherwise you can't use the color.

inlineFrame (true)

If enabled, shows a border and background when inline. Disabling may allow closer integration.

layout ({ ... })

Set the position of elements in a table layout. You could create any layout possible with HTML tables by specifying cell position and size of each part. @todo document how this works.

limit ('')

Limit the selectable colors to any of the predefined limits:

• '' No limitations, allow 8bpp color for a palette of all 16 million colors.
• websafe Set of 216 colors composed of 00, 33, 66, 99, cc and ff color channel values in #rrggbb.
• nibble 4 bits per color, can be easily converted to #rgb format. The palette is limited to 4096 colors.
• binary Allow only #00 or #ff as color channel values for primary colors only; only 8 colors are available with this limit.
• name Limit to closest color name.

modal (false)

Ensures no other controls on screen can be used while the dialog is opened. Also look at showCancelButton and closeOnEscape to use in combination with the modal option. closeOnOutside is redundant when used with modal.

mode ('h')

Determines the functionality of the map and bar components. Allowed values are; 'h', 's', 'l', 'r', 'g', 'b' or 'a', for hue, saturation, luminosity, red, green, blue and alpha respectively.

okOnEnter (false)

Close the window when pressing the Enter key on the keyboard, keeping the selected color.

parts ('')

Determine which parts to display. Use any of the preset names ('full', 'popup' or 'inline') or specify an array of part names (i.e. ['header', 'map', 'bar', 'hex', 'hsv', 'rgb', 'alpha', 'lab', 'cmyk', 'preview', 'swatches', 'footer']). If an empty string is given, the parts will be automatically chosen as preset 'popup' or 'inline' depending on the context in which the colorpicker is used.

regional ('')

Sets the language to use. Note that you must load the appropriate language file from the i18n directory. '' is included by default.

revert (false)

If enabled, closing the dialog through any means but the OK button will revert the color back to the previous state, as if pressing the Cancel button. The revert option changes the behaviour of the [X] button in the header, the Escape keyboard button and clicking outside the dialog, when any of these features are enabled.

rgb (true)

Whether or not to show the inputs for RGB.

showAnim ('fadeIn')

Same as jQueryUI DatePicker.

showCancelButton (true)

Show the Cancel button if buttonpane is visible.

showCloseButton (true)

Show the Close button if the header is visible. If the dialog is inline, the close button is never shown.

showNoneButton (false)

Show the None/Revert button if buttonpane is visible.

showOn ('focus click alt')

Specifies what user events will show the colorpicker if not inline. Specify multiple events by seperating with space. Optionally 'focus', 'click', 'alt', 'button' and/or 'both'

• focus When the element comes into focus (either tab or click)
• click When the element is clicked (for non-inputs)
• alt When clicking on an element specified with as altField
• button When clicking on the button created if this event is specified.
• both selects all possible triggers

showOptions ({})

Same as jQueryUI DatePicker.

swatches (null)

'null' to show swatches of HTML colors or provide your own object with colornames and {r:1, g:1, b:1} array. For example { 'red': {r:1, g:0, b:0}, 'blue': {r:0, g:0, b:1} } Alternatively, load a predefined set of swatches and specify the name. For example, for the pantone set, specify 'pantone'.

swatchesWidth (84)

Width of the swatches display in pixels.

title (null)

Title to display in the header. If null, use language default.

Events

init

Triggered on initially setting the color. Called only once. Callbacks recieve same data as select event.

close

Triggered when the popup is closed. Callbacks recieve same data as select event and an additional number of fields containing the current color in all supported color spaces. These are rgb{}, hsv{}, cmyk{}, lab{}, hsl{} and a. Most values are floating point numbers in range [0,1] for accuracy. The a and b values in the lab color space have range [-1,1].

select

Triggered on each change, confirmation (click on OK button) and cancellation (click on Cancel, outside window or window close button) respectively.

The event recieves a jQuery event object and a data object containing the elements 'formatted' (with the color formatted according to formatColor).

Note that select may be triggered in rapid succession when dragging the mouse accross the map or bar and may be triggered without a change in color upon specific user interactions.

Methods

open

Open the dialog

close

Close the dialog

destroy

Destroy the widget

setColor

Set the current color to the specified color. Accepts any CSS-confirming color specification.

Plugins

Colorpicker is extensible with several types of plugins. A number of plugins is provided for use. The plugins are constructed such that you only need to load the javascript file after the Colorpicker plugin itself is loaded.

limits

Limits let you limit the possible colors, as used by the 'limit' option.

No plugins included.

parsers

Parser take a textual representation of a color and return a Color object. If no match is found, nothing is returned and the next parser is tried. Parsers are tried in order of appearance.

Included plugins:

• cmyk-parser Parses a cmyk(c, y, m, k) format, similar to rgba.
• cmyk-percentage-parser Parses a cmyk(c%, y%, m%, k%) format with percentages.

parts

You can add additional visual parts, usually controls, that interact with the rest of Colorpicker framework.

Included plugins:

• memory Cookie-based memory nodes.
• rgbsliders Set of three red/green/blue sliders with dynamically adjusted gradients.

partslists

Partslists are a convenient way to select multiple parts at once without having to specify each one individually.

No plugins included.

regional

Regional (in the i18n directory) plugins contain localized texts (a.k.a. translations). A number of languages is provided.

Included regionals:

• de German (Deutsch).
• en English (default).
• fr French (Francais).
• nl Dutch (Nederlands).
• pt-br Brazilian Portuguese.

swatches

Swatches are collections of predefined and named colors. By default the standard html colors are loaded.

Included plugins:

• crayola Crayola pencil color names
• pantone Pantone color codes
• ral-classic Classic RAL paint numbers

writers

Writers take a Color object and output a textual representation of the color. Writers are used for the colorFormat option.

No plugins included.

Objects

Colorpicker uses a Color object internally to represent a color and convert between the supported color models. You can create a new Color object through $.colorpicker.Color.
