Typst supports:
- sRGB through the
rgbfunction - Device CMYK through
cmykfunction - D65 Gray through the
lumafunction - Oklab through the
oklabfunction - Oklch through the
oklchfunction - Linear RGB through the
color.linear-rgbfunction - HSL through the

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. Most of these color maps are chosen to be color blind friendly.
| 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!
定义
函数和类型可以有与其关联的定义 (成员或方法)。可以使用 "." 操作符来访问调用它们。
luma

A grayscale color is represented internally by a single lightness
component.

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 (

linear-rgb
Create an RGB(A) color with linear luma.
This color space is similar to sRGB, but with the distinction that the
color component are not gamma corrected. This makes it easier to perform
color operations such as blending and interpolation. Although, you
should prefer to use the oklab function for these.
A linear RGB(A) color is represented internally by an array of four components:

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:

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.
