The ColorPicker Module adds a color-picker input field to the SilverStripe CMS. It makes use of the ColorPicker jQuery Plugin.


  • Extract all files into the 'colorpicker' folder under your Silverstripe root, or install using composer
composer require "tractorcow/silverstripe-colorpicker" "3.0.*@dev"


Here's how you define a DB field to be a color:

private static $db = array(
    'BgColor' => 'Color'

That's all... scaffolding will take care of creating the appropriate form-field.

If you use getCMSFields to create your fields yourself, you might want to do something like this:

public function getCMSFields()
    $fields = parent::getCMSFields();

    	new ColorField('BgColor', 'Background color')

    return $fields;

Tips for using the Color fieldtype in templates

The Color fieldtype provides some helper methods that can be useful in templating. Let's consider the above scenario where you have a Field named 'BgColor'. The most common use-case is something like this:

<body style="background-color: #$BgColor;">

But there's more. You could also use CSS3 rgba color definitions with alpha. Example:

<body style="background-color: #$BgColor; background-color: $BgColor.CSSColor(0.5);">

This will color your background with an alpha value of 0.5 (browsers that don't support rgba, such as IE-8 will fall back to the first background-color definition, that's why it's still in there).

Here's a complete list of the Color methods available in templates:

  • Red returns the red color component
  • Green returns the green color component
  • Blue returns the blue color component
  • CSSColor returns the color as rgba. The alpha value can be specified with the (optional) argument.
  • Luminance the luminance of the color as a floating-point value ranging from 0-1
  • Blend blends the color with a second background color (defaults to #FFFFFF) with the given opacity. $BGColor.Blend(0.5, '#000000') will give the color 50% opacity and put it on top of a black background.
  • AlteredColorHSV modifies the current color by the given HSV values. These values are offsets, so you could do something like this: $BgColor.AlteredColorHSV(0.5, 0, 0) which will return the color with the opposite hue. All parameters are percentage based and range from 0 - 1. So doing: $BgColor.AlteredColorHSV(0, 0, -0.2) will result in a color with 20% less brightness (absolute, not relative).
