Some functions about RGB codes.

函数：

contrast –

Get the contrasting color of a RGB code.
transition –

Transition one color to another proportionally.
blend –

Mix colors by weight.
gradient –

Get a list of color gradients from one color to another proportionally.

contrast ¶

contrast(
    value: tuple[int, int, int], /, *, channels: tuple[bool, bool, bool] = (True, True, True)
) -> tuple[int, int, int]

Get the contrasting color of a RGB code.

value: a RGB code
channels: three color channels

transition ¶

transition(
    first: tuple[int, int, int],
    second: tuple[int, int, int],
    rate: float,
    *,
    channels: tuple[bool, bool, bool] = (True, True, True)
) -> tuple[int, int, int]

Transition one color to another proportionally.

first: the first RGB code
second: the second RGB code
rate: transition rate
channels: three color channels

blend ¶

blend(*values: tuple[int, int, int], weights: list[float] | None = None) -> tuple[int, int, int]

Mix colors by weight.

values: RGB codes
weights: weight list, default value indicates the same weights

gradient ¶

gradient(
    first: tuple[int, int, int],
    second: tuple[int, int, int],
    count: int,
    rate: float = 1,
    *,
    channels: tuple[bool, bool, bool] = (True, True, True),
    contoller: collections.abc.Callable[[float], float] = controllers.linear
) -> list[tuple[int, int, int]]

Get a list of color gradients from one color to another proportionally.

first: the first RGB code
second: the second RGB code
count: the number of gradients
rate: transition rate
channels: three color channels
controller: control function
