sample_uniform_hue_colors 

sample_uniform_hue_colors(num_colors: int, saturation: float = 1.0, brightness: float = 1.0) -> List[List[int]]

Hue space에서 동일한 간격으로 서로 다른 색들을 샘플링합니다.

Parameters:

  • num_colors (int) –

    number of colors to sample

  • saturation (float, default: 1.0 ) –

    saturation. Defaults to 1.0.

  • brightness (float, default: 1.0 ) –

    value. Defaults to 1.0.

Returns:

  • List[List[int]] –

    List[List[int]]: [num_colors x [R, G, B]]
