The color palette app is part of Airtable Apps, a Pro plan feature. Apps let you extend the functionality of your bases: you can use apps to bring new information into Airtable, visualize and summarize your records in colorful ways, and even directly integrate your Airtable bases with your favorite apps.
Color palette allows you to pull HEX, RGB or HSL codes and color names from your base and turn them into a palette. You can also copy each color code type into your clipboard, allowing seamless collaboration between teams.
In order to use the color palette app, you need a field containing names for your swatches, and a field containing color codes. The color codes can be HEX, RGB or HSL.
When you install your color palette app, you'll automatically get brought to the new app's settings page. From here, you can specify the appropriate table and view, the field for your swatch names, and the field for your color codes.
When viewing the live version of your app in the apps panel or the fullscreen dashboard, you can click on any color's RGB, HEX, or HSL code to copy that code to your clipboard.
