Create custom colour palettes with flexibility & control.

Colour Swatches plugin for Craft CMS 4+

Instead of providing a user a full color picker, Colour Swatches is a configurable a fieldtype that gives an admin the ability to provide a selection of colours for a user to choose from. This allows you to create branded colour palettes with a bank of classnames ready to use in your templates.

Requirements

This plugin requires Craft CMS 4.0.0 or later.

Installation

To install the plugin, follow these instructions.

Open your terminal and go to your Craft project:
```
 cd /path/to/project
```

Then tell Composer to load the plugin:

 composer require percipiolondon/craft-colour-swatches

In the Control Panel, go to Settings → Plugins and click the "Install" button for Colour Swatches.

Configuring Colour Swatches

Using the field settings

Create a Colour Swatches field and provide label and hex value options. Multiple colours are possible by seperating them with a comma.

When using Colour Swatches with the field settings

You can access both the label and color in your template. By default, the label will display:

    {{ fieldName }}
    {{ fieldName.label }}
    {{ fieldName.color }}

    {% for color in fieldName.color %}
        {{ color.color }}
    {% endfor %}

If you want more granular control with your colour palettes, use the configuration file option below.

Using the config file

You can use a config/colour-swatches.php config file file to predefine the possible colours, define different palettes and add lables, classnames or other attributes to your colours.

Take a look at the config file in this repo for an example.

In your field settings you can then have the possibility to have it use the predefined colours.

Making changes to your config file

If have entries using Colour Swatches and you make changes to your config file, you will need to resave your entries for new information from your config file to be pulled into your entry data.

From the command line you can run Crafts ./craft resave/entries and your entries will be populated with any changes to from your colour-swatches.php config file. Colour swatches uses the label value to map changes to the entries, so make sure your labels values are unique / not null.

Using Colour Swatches

You can access both the label and color in your template. By default, the label will display:

    {{ fieldName }}
    {{ fieldName.label }}
    {{ fieldName.color }}
    {{ fieldName.customAttribute }}

If you're using multiple colours you will need to loop through your color array

    {% for field in fieldName.color %}
        {{ field.color }}
        {{ field.customAttribute }}
    {% endfor %}

GraphQL

Colour Swatches comes with GraphQL support you can build a query as follows:

fieldName {
        label
        class
        color
      }

which will give you the following result if you use the config file:

"fieldName": {
          "label": "Black/White",
          "class": "",
          "color": [
            "{\"color\":\"#000000\",\"background\":\"bg-black\"}",
            "{\"color\":\"#ffffff\",\"text\":\"text-white\"}"
          ]
        },

or in case of a single value added through the settings you will see:

"fieldName": {
          "label": "Black",
          "class": "",
          "color": [
            "#000000"
          ]
        },
