Custom Gutenberg Color Palettes

The default Gutenberg color palettes are pretty basic. There’s also a way to add a ‘custom’ color but I don’t really want to go hunting for a HEX color code every-time I need it.

So, like the true nerdy coding artist that I am, I decided to customize my color palette to match my favorite Procreate colors from my #the100dayproject in 2020!

When you’re viewing the color palettes in Procreate if you select the ‘Value’ view it displays your Hexadecimal value, so handy!

The Code – Change your Gutenberg color palette!

Instead of adding all of this to my functions.php file I created a new file called ‘color-palettes.php’ and then I added it to the top of my functions.php so it’s pulled into the theme:

/** Custom Gutenberg Colors */
require get_template_directory() . '/inc/color-palettes.php';

And then in my color-palettes.php file I defined all my names and colors:

* Custom Gutenberg Colors

function add_custom_colors() {
	'name'  => esc_html__( 'Dark Gray', 'ah' ),
	'slug'  => 'dark-gray',
	'color' => '#212321',
	'name'  => esc_html__( 'Grayish White', 'ah' ),
	'slug'  => 'grayish-white',
	'color' => '#dfded9',
	'name'  => esc_html__( 'Off White', 'ah' ),
	'slug'  => 'off-white',
	'color' => '#f1f1ec',
	'name'  => esc_html__( 'Leafy Green', 'ah' ),
	'slug'  => 'leafy-green',
	'color' => '#61b05a',
	'name'  => esc_html__( 'Dark Green', 'ah' ),
	'slug'  => 'dark-green',
	'color' => '#309974',
	'name'  => esc_html__( 'Bright Pink', 'ah' ),
	'slug'  => 'bright-pink',
	'color' => '#f07a7c',
	'name'  => esc_html__( 'Medium Pink', 'ah' ),
	'slug'  => 'medium-pink',
	'color' => '#ffa3a4',
	'name'  => esc_html__( 'Light Pink', 'ah' ),
	'slug'  => 'light-pink',
	'color' => '#fbcec3',
	'name'  => esc_html__( 'Peach', 'ah' ),
	'slug'  => 'peach',
	'color' => '#fab093',
	'name'  => esc_html__( 'Goldy', 'ah' ),
	'slug'  => 'goldy',
	'color' => '#e6be41',
	'name'  => esc_html__( 'Reddish', 'ah' ),
	'slug'  => 'reddish',
	'color' => '#e04e33',
	'name'  => esc_html__( 'Blue Green', 'ah' ),
	'slug'  => 'blue-green',
	'color' => '#1888a8',
	'name'  => esc_html__( 'Brown', 'ah' ),
	'slug'  => 'brown',
	'color' => '#9a604b',
	'name'  => esc_html__( 'Light Brown', 'ah' ),
	'slug'  => 'light-brown',
	'color' => '#c88d51',
	'name'  => esc_html__( 'Rusty Orange', 'ah' ),
	'slug'  => 'rusty-orange',
	'color' => '#d87e1d',

add_action( 'after_setup_theme', 'add_custom_colors' );

That added the colors to the editor but we still need to add those colors to our theme’s CSS. Warning! This part took forever. Copy. Paste. Copy. Paste.

Once I saved everything and cleared my cache and refreshed my admin post page the new colors appeared and they are giving me all the heart eyes. ๐Ÿ˜ ๐Ÿ˜ ๐Ÿ˜
