Predefined colors
Typst defines the following built-in colors:
| Color | Definition |
|---|---|
black | luma(0) |
gray | luma(170) |
silver | luma(221) |
white | luma(255) |
navy | rgb("#001f3f") |
blue | rgb("#0074d9") |
aqua | rgb("#7fdbff") |
teal | rgb("#39cccc") |
eastern | rgb("#239dad") |
purple | rgb("#b10dc9") |
fuchsia | rgb("#f012be") |
maroon | rgb("#85144b") |
red | rgb("#ff4136") |
orange | rgb("#ff851b") |
yellow | rgb("#ffdc00") |
olive | rgb("#3d9970") |
green | rgb("#2ecc40") |
lime | rgb("#01ff70") |
The predefined colors and the most important color constructors are
available globally and also in the color type's scope, so you can write
either color.red or just red.
Predefined color maps
Typst also includes a number of preset color maps that can be used for
gradients. These are simply arrays of colors defined in
the module color.map.
#circle(fill: gradient.linear(..color.map.crest))
| Map | Details |
|---|---|
turbo | A perceptually uniform rainbow-like color map. Read this blog post for more details. |
cividis | A blue to gray to yellow color map. See this blog post for more details. |
rainbow | Cycles through the full color spectrum. This color map is best used by setting the interpolation color space to HSL. The rainbow gradient is not suitable for data visualization because it is not perceptually uniform, so the differences between values become unclear to your readers. It should only be used for decorative purposes. |
spectral | Red to yellow to blue color map. |
viridis | A purple to teal to yellow color map. |
inferno | A black to red to yellow color map. |
magma | A black to purple to yellow color map. |
plasma | A purple to pink to yellow color map. |
rocket | A black to red to white color map. |
mako | A black to teal to yellow color map. |
vlag | A light blue to white to red color map. |
icefire | A light teal to black to yellow color map. |
flare | A orange to purple color map that is perceptually uniform. |
crest | A blue to white to red color map. |
Some popular presets are not included because they are not available under a free licence. Others, like Jet, are not included because they are not color blind friendly. Feel free to use or create a package with other presets that are useful to you!
定義
Functions and types and can have associated definitions. These are accessed by specifying the function or type, followed by a period, and then the definition's name.
luma

A grayscale color is represented internally by a single lightness
component.
These components are also available using the
components method.

oklab
Create an Oklab color.
This color space is well suited for the following use cases:
- Color manipulation such as saturating while keeping perceived hue
- Creating grayscale images with uniform perceived lightness
- Creating smooth and uniform color transition and gradients
A linear Oklab color is represented internally by an array of four components:
- lightness (
ratio) - a (
floatorratio. Ratios are relative to0.4; meaning50%is equal to0.2) - b (

color operations such as blending and interpolation. Although, you
should prefer to use the oklab function for these.

Extracts the components of this color.
The size and values of this array depends on the color space. You can
obtain the color space using space. Below is a table
of the color spaces and their components:
| Color space | C1 | C2 | C3 | C4 |
|---|---|---|---|---|
luma | Lightness | |||
oklab | Lightness | a | b | Alpha |
oklch | Lightness | Chroma | Hue | Alpha |
linear-rgb | Red | Green | Blue | Alpha |
rgb | Red | Green | Blue | Alpha |
cmyk | Cyan | Magenta | Yellow | Key |
hsl | Hue | Saturation | Lightness | Alpha |
hsv | Hue | Saturation | Value | Alpha |
For the meaning and type of each individual value, see the documentation
of the corresponding color space. The alpha component is optional and
only included if the alpha argument is true. The length of the
returned array depends on the number of components and whether the alpha
component is included.
View example
// note that the alpha component is included by default
#rgb(40%, 60%, 80%).components()
alpha
Whether to include the alpha component.
Default:true
space
Returns the constructor function for this color's space:
View example
#let color = cmyk(1%, 2%, 3%, 4%)
#(color.space() == cmyk)
to-hex
Returns the color's RGB(A) hex representation (such as #ffaa32 or
#020304fe). The alpha component (last two digits in #020304fe) is
omitted if it is equal to ff (255 / 100%).
lighten
Lightens a color by a given factor.
factor
The factor to lighten the color by.
darken

factor
The factor to darken the color by.

factor
The factor to saturate the color by.
desaturate
Decreases the saturation of a color by a given factor.
factor
The factor to desaturate the color by.
negate
Produces the complementary color using a provided color space. You can think of it as the opposite side on a color wheel.
View example
#square(fill: yellow)
#square(fill: yellow.negate())
#square(fill: yellow.negate(space: rgb))
space
any
The color space used for the transformation. By default, a perceptual color space is used.
Default:oklab
rotate
Rotates the hue of the color by a given angle.
angle
The angle to rotate the hue by.
space
any
The color space used to rotate. By default, this happens in a perceptual
color space (oklch).
Default:oklch
mix
Create a color by mixing two or more colors.
In color spaces with a hue component (hsl, hsv, oklch), only two colors can be mixed at once. Mixing more than two colors in such a space will result in an error!
View example
#set block(height: 20pt, width: 100%)
#block(fill: red.mix(blue))
#block(fill: red.mix(blue, space: rgb))
#block(fill: color.mix(red, blue, white))
#block(fill: color.mix((red, 70%), (blue, 30%)))
colors
The colors, optionally with weights, specified as a pair (array of length two) of color and weight (float or ratio).
The weights do not need to add to 100%, they are relative to the
sum of all weights.
space
any
The color space to mix in. By default, this happens in a perceptual
color space (oklab).
Default:oklab
transparentize
Makes a color more transparent by a given factor.
This method is relative to the existing alpha value.
If the scale is positive, calculates alpha - alpha * scale.
Negative scales behave like color.opacify(-scale).
View example
#block(fill: red)[opaque]
#block(fill: red.transparentize(50%))[half red]
#block(fill: red.transparentize(75%))[quarter red]
scale
The factor to change the alpha value by.
opacify
Makes a color more opaque by a given scale.
This method is relative to the existing alpha value.
If the scale is positive, calculates alpha + scale - alpha * scale.
Negative scales behave like color.transparentize(-scale).
View example
#let half-red = red.transparentize(50%)
#block(fill: half-red.opacify(100%))[opaque]
#block(fill: half-red.opacify(50%))[three quarters red]
#block(fill: half-red.opacify(-50%))[one quarter red]
scale
The scale to change the alpha value by.
