Colors

Slab color styling starts in Theme settings > Colors. Merchants pick a small set of global colors, then Slab generates additional color tokens (such as accents, shades, neutral, and plain) that sections and blocks can use through color scheme settings.

How to change theme colors

Configure base colors

Open Theme settings > Colors.
Select and edit your base colors such as Background, Foreground, Error, Success, Mobile bar, and Overlay background.

Configure color schemes

Open Theme settings > Colors.
Under Schemes, edit Scheme 1 and Scheme 2 first.
Click Add Scheme if you need more brand variations.
For each scheme, set all six fields: background, foreground, border, hover background, hover foreground, and hover border.

Apply colors to your sections and blocks

Open the theme editor and select the block or section you'd like to edit
Find the color settings and select Base or Custom for the Type option
Selecting Base will show generated base colors such as Accents and Shades.
Selecting Custom will let you choose any color scheme

Generated color options

After you choose your global colors, Slab automatically creates extra color variations so sections and blocks stay visually consistent.

Accent 1/2/3: Layered overlay tones used for depth and emphasis.
Shade 1/2/3: Lighter or darker background steps for subtle contrast.
Main: The main emphasis style for a component, based on the body foreground color.
Plain: A softer, low-emphasis surface based on the body background.
If your body background is light, Slab creates darker overlays and shade tones.
If your body background is dark, Slab creates lighter overlays and shade tones.

Color settings

Base

These settings define your store's base color system.

Setting	What it controls
Background	Main storefront background and the base used for generated shade/overlay tones.
Foreground	Default text color and default border contrast for base surfaces.

Schemes

In Theme settings > Colors > Schemes, you can edit Scheme 1, Scheme 2, and add as many additional schemes as needed.

Each scheme has the same six color fields:

Setting	How it is applied
Background	Main background color for any section or block using that scheme.
Foreground	Text/icon color used on top of that scheme background.
Border	Default border color for elements using that scheme.
Hover background	Hover background for buttons and interactive elements in that scheme.
Hover foreground	Hover text/icon color for interactive elements in that scheme.
Hover border	Hover border color for interactive elements in that scheme.

Important: editing a scheme updates every section and block that uses that scheme.

Utility

These settings control utility and supporting colors.

Setting	What it controls
Error	Error surfaces and error feedback color.
Success	Success surfaces and success feedback color.
