MC Picker

a minimal color picker

Just add the script and the colorpicker will work on any input[type=color]. Even if you add them to DOM afterwards.

The implementation is minimal, the code is minimal, even the colorpicker itself is a mere six elements in a wrapper and some smart CSS.

Installation

To install do npm i -S mc_picker or yarn add mc_picker -S and import it somewhere: import 'mc_picker'.

Or load into HTML directly from CDN with <script src="https://unpkg.com/mc_picker"></script>.

Datalist

The input[type=color] can have a related dataList. These are shown as swatch options at the top of the color picker. The options are not validated against so the regular interface is still functional.

Alpha channel

Although input[type=color] does not support alpha channels, you can add this by setting [data-alpha=255]. The value ranges from 0 to 255 and updates when changed. The input value itself is still the regular rgb format so you'll have to concat it from the data-attribute yourself, or use the API.

API

When activated, each input element exposes a color object: document.querySelector('input').color. All instances are also exposed on globalThis.pickers; a map with the HTMLInputElement as key.

Customisation

You can easily adjust dimensions through CSS without affecting functionality:

.mcpicker {
  --mcp-w: 20rem;
  --mcp-h: 20rem;
  --mcp-gutter: 2rem;
  --mcp-font-size: 1.2rem;
}

This can also be done for a single instance when you use .mcpicker_[color input id] instead of .mcpicker.
