Which variables does the block override?

Bootstrap's theme-color roles — primary, secondary, success, danger, warning, info — plus the surface variables, exactly the names the framework's components consume.

Do I need SCSS, or does plain CSS work?

The block is plain variable declarations, consumable wherever Bootstrap's variables are customized — SCSS builds override before compile; CSS-only setups use the runtime custom property layer.

What if my palette lacks a state color?

Bootstrap's semantic slots need casting — derive a success or danger from your palette's family with the harmony tools, or keep the framework defaults for states and cast only the brand roles.

Will upgrades to Bootstrap break the block?

No — the block overrides documented variables, which is the supported customization path and stays stable across minor upgrades.

What happens when the brand palette changes?

The export is a snapshot: regenerate the block from the new palette and swap it in. That is the point of keeping the values generated rather than hand-edited — the role names stay put while the values move.

The Bootstrap color exporter turns a palette into the theme-color variables Bootstrap 5 consumes — the bootstrap theme colors scss block, convention-ready.

What is Bootstrap Color Exporter?

Bootstrap's theming hangs on a short list of theme colors — primary, secondary, success, danger, warning, info — plus the surface pair, all declared as variables the framework's components consume. The Bootstrap color exporter emits that block from an editable palette: assign your colors to the roles, and the tool generates the variable declarations in Bootstrap's convention, copy-ready for the theme file. It is the bootstrap 5 color variables block, on-contract.

The role mapping is the tool's real work.
Bootstrap's slots are semantic — success must read as success, danger as danger — so the export is an act of casting, not formatting: which palette member becomes primary, which neutral becomes secondary, which accents take the state roles.
The editor rows carry the role names, the block regenerates as the casting changes, and the pasted result plugs into Bootstrap's variable chain — after which components, buttons and utilities inherit the palette without further edits.
That is the bootstrap theme colors scss promise: one block, the whole framework re-skinned.

The workflow it serves is the Bootstrap project meeting a brand: the framework ships sane defaults that read as generic Bootstrap, and the fastest path to a branded build is the variables block, not overrides scattered through custom CSS. Editing lives in the rows; the export stays conventional; upgrades stay safe because the block overrides variables rather than fighting compiled CSS. The shadcn exporter serves that ecosystem's convention; the generic CSS variables exporter serves framework-agnostic stylesheets; the token exporters feed pipelines that transform rather than override.

Bootstrap's theming hook is deliberately simple: a map of named colours, each of which becomes a family of classes, buttons, alerts and utilities at build time.
That makes the names the real decision — calling something primary or danger rather than brand-blue is what lets the framework's components wire themselves up, and it means a later change of hex does not require a search across templates.
The supplied family also has to satisfy the framework's own assumptions about contrast, since the components expect each colour to carry text at a given weight, and a mapped hue that is too light produces buttons whose labels are unreadable without any warning at build time.
Generating the block from a palette keeps the names conventional and the values deliberate, which is the combination that makes a themed Bootstrap build look designed rather than rebuilt.

As a bootstrap palette variables export instrument it is deliberately the casting tool: a palette in, the theme-colors block out, roles assigned and names conventional. For Bootstrap 5 projects starting from a brand palette, it is the shortest path from brand guideline to a framework that looks like it was always yours.

Where the framework needs a colour the brand does not supply — a warning, a muted surface — take it from the generated ramp rather than inventing one, so the set stays inside the same family while still satisfying the roles Bootstrap expects, and the theme's exceptions remain visible instead of hidden inside the map.

How to use Bootstrap Color Exporter

Assign palette colors to Bootstrap's roles — primary, secondary, the states, surfaces.
Watch the variable block generate in Bootstrap's convention.
Copy it into your theme overrides; components and utilities inherit the cast.

When to use Bootstrap Color Exporter vs related tools

Use this to brand a Bootstrap 5 project from a palette. Use the shadcn exporter for that ecosystem, the generic CSS variables exporter for custom stylesheets, and the contrast checker to verify text roles against the cast surfaces. The framework's own theme values are laid out in the Bootstrap color reference, and when the build compiles Sass the same tokens can be written as build-time variables by the SCSS variable generator.
