Uses the :d65 reference illuminant.

Summary

t()

Defines the channels in an OKLab color.

Converts from sRGB to OKLab.

new(channels)

Generates a new OKLab color

new(l, a, b)

Generates a new OKLab color

new(l, a, b, a_)

Generates a new OKLab color

Converts from OKLab to sRGB.

@type t() :: %{l_: number(), a_: number(), b_: number(), a: number()}

Defines the channels in an OKLab color.

@spec from_rgb(Ultraviolet.Color.t(), [...]) :: {:ok, t()}

Converts from sRGB to OKLab.

:round: an integer if rounding L, a, and b channel values to N decimal places is desired; if no rounding is desired, pass false. Default: 2

@spec new(tuple() | [number()] | map() | [...]) :: {:ok, t()}

Generates a new OKLab color

iex>Ultraviolet.Color.OKLab.new({0.5, 0.0, 0.0})
{:ok, %Ultraviolet.Color.OKLab{l_: 0.5, a_: 0.0, b_: 0.0}}

@spec new(number(), number(), number()) :: {:ok, t()}

Generates a new OKLab color

iex>Ultraviolet.Color.OKLab.new(0.5, 0.0, 0.0)
{:ok, %Ultraviolet.Color.OKLab{l_: 0.5, a_: 0.0, b_: 0.0}}

@spec new(number(), number(), number(), number()) :: {:ok, t()}

Generates a new OKLab color

iex>Ultraviolet.Color.OKLab.new(0.5, 0.0, 0.0, 0.5)
{:ok, %Ultraviolet.Color.OKLab{l_: 0.5, a_: 0.0, b_: 0.0, a: 0.5}}

@spec to_rgb(t(), [...]) :: {:ok, Ultraviolet.Color.t()}

Converts from OKLab to sRGB.

:round: an integer if rounding r, g, and b channel values to N decimal places is desired; if no rounding is desired, pass false. Default: 0
