Tailwind CSS v4 ships a default palette of named color families, from red and blue to neutrals like slate, zinc and stone, each in 11 shades from 50 (lightest) to 950 (darkest), plus black and white. Version 4 defines every shade in OKLCH as a CSS variable such as --color-blue-500, which you use as bg-blue-500.
| You write | You get |
|---|---|
| bg-blue-500 | background-color: var(--color-blue-500) |
| text-slate-900 | color: var(--color-slate-900) |
| border-rose-300 | border-color: var(--color-rose-300) |
| bg-sky-500/50 | The same color at 50% opacity |
| var(--color-blue-500) | oklch(62.3% 0.214 259.815) in your own CSS |

Variables in the --color- namespace become utilities. Here bg-brand-500 and text-ink start working alongside the defaults.
@import "tailwindcss";
@theme {
--color-brand-50: oklch(97% 0.02 250);
--color-brand-500: oklch(62% 0.19 250);
--color-brand-900: oklch(30% 0.09 250);
--color-ink: #1b1b1f;
}Setting a namespace to initial drops it. The first line removes one family; the second would remove every default color.
@theme {
--color-lime-*: initial;
/* --color-*: initial; */
}A pale background and a dark text shade from one family, plus a border two steps darker than the background.
<div class="rounded-xl border border-emerald-200 bg-emerald-50 p-4 text-emerald-900">
Your order has shipped.
</div>Handy for third-party widgets you cannot add classes to.
.legacy-widget {
color: var(--color-slate-800);
border-color: var(--color-slate-200);
background: var(--color-white);
}The number tracks lightness, not saturation. 50 is close to white and 950 close to black, with 500 roughly the pure hue. Because each family follows the same scale, swapping blue-600 for violet-600 keeps a button's contrast about the same.
Neutrals differ only in their undertone: slate leans blue, zinc is slightly cool, neutral has no hue at all and stone is warm. Version 4 adds more tinted neutrals such as mauve, olive, mist and taupe.
Any default can be redefined in @theme by writing the same variable name with a new value. Every utility that uses it picks up the change, which is handy for nudging one shade to match a brand without replacing the family.
Keep overrides rare. The defaults are tuned as a set, and a lone shade from somewhere else can break the even steps between neighbours.
Version 4 defines its palette in OKLCH, whose L channel is perceived lightness, so shades can be spaced by how light they look. It also reaches more vivid colors on wide-gamut screens. The oklch() function has worked across major browsers since May 2023, so browsers read the values directly.
Declare a variable in the --color- namespace inside @theme in your CSS, for example --color-midnight: #121063. Tailwind then generates bg-midnight, text-midnight and the rest. No tailwind.config.js entry is needed.
Set the family to initial inside @theme, for example --color-lime-*: initial. That removes every lime shade from the generated utilities and variables.
Add a slash and an opacity to the class: bg-sky-500/50 for 50%, or an arbitrary value like bg-pink-500/[71.37%]. In your own CSS, the --alpha() function does the same with a variable.
Yes. Every palette color is exposed as a CSS variable, so color: var(--color-blue-500) works in any stylesheet that loads Tailwind.
