3.18 color🔗

Usage:
include color
import color as ...
Note: it is discouraged to use the include form of importing this library, since this library defines many names, some of which will likely conflict with existing names. (For instance, tan is both a color and a mathematical function.) Use the import form instead. See import and Module Identifiers for more detail.

3.18.1 Data types🔗

data Color:
| color(red :: Number, green :: Number, blue :: Number, alpha :: Number)
end

color :: (
red :: Number,
green :: Number,
blue :: Number,
alpha :: Number
)
-> Color

The values for red, green, and blue should be in the range 0–255, inclusive. The values for alpha should be in the range 0–1, and indicates how transparent the color is, with 0 as fully transparent and 1 as fully opaque.

Note that the library does not enforce these range restrictions when constructing custom colors, so that you can manipulate colors arithmetically (e.g. modeling “additive color” by literally adding components together). The rendering of these colors will clamp the values into those ranges, so e.g. color(500, 255, 0, 1) will look the same as yellow itself, but the values will not be equal.
