Color

class compas.colors.Color(red, green, blue, alpha=1.0, **kwargs)[source]

Bases: Data

Class for working with colors.

Parameters

red (float) – The red component in the range of 0-1.
green (float) – The green component in the range of 0-1.
blue (float) – The blue component in the range of 0-1.
alpha (float, optional) – Transparency setting. If alpha = 0.0, the color is fully transparent. If alpha = 1.0, the color is fully opaque.

Other Parameters

**kwargs (dict, optional) – See Data for more information.

Attributes

r (float) – Red component of the color in RGB1 color space.
g (float) – Green component of the color in RGB1 color space.
b (float) – Blue component of the color in RGB1 color space.
rgb (tuple[float, float, float]) – RGB1 color tuple, with components in the range 0-1.
rgb255 (tuple[int, int, int]) – RGB255 color tuple, with components in the range 0-255.
hex (str) – Hexadecimal color string.
hls (tuple[float, float, float]) – Hue, Lightness, Saturation.
hsv (tuple[float, float, float]) – Hue, Saturation, Value / Brightness.
lightness (float) – How much white the color appears to contain. This is the “Lightness” in HLS. Making a color “lighter” is like adding more white.
brightness (float) – How well-lit the color appears to be. This is the “Value” in HSV. Making a color “brighter” is like shining a stronger light on it, or illuminating it better.
is_light (bool) – If True, the color is considered light.

Examples

>>> Color.navy()
Color(0.0, 0.0, 0.5, 1.0)
>>> Color.olive()
Color(0.5, 0.5, 0.0, 1.0)

>>> Color.lime().is_light
True
>>> Color.navy().is_light
False
