Colors

Named-colors

SİMETRİ provides a comprehensive list of colors that can be used in your designs. These colors can be accessed by using sg.color_name. The chart of all available named-colors is shown below.

These names come from the xkcd color survey

The colors are defined in the CSS Color Module Level 4 specification. The list is not exhaustive, and you can always define your own colors using RGB or HEX values.

colorsys -- Conversions between color systems (from Python 3.13.3 documentation)

colorsys — Conversions between color systems Source code: Lib/colorsys.py

The colorsys module defines bidirectional conversions of color values between colors expressed in the RGB (Red Green Blue) color space used in computer monitors and three other coordinate systems: YIQ, HLS (Hue Lightness Saturation) and HSV (Hue Saturation Value). Coordinates in all of these color spaces are floating-point values. In the YIQ space, the Y coordinate is between 0 and 1, but the I and Q coordinates can be positive or negative. In all other spaces, the coordinates are all between 0 and 1.

See also More information about color spaces can be found at https://poynton.ca/ColorFAQ.html and https://www.cambridgeincolour.com/tutorials/color-spaces.htm. The colorsys module defines the following functions:

colorsys.rgb_to_yiq(r, g, b): Convert the color from RGB coordinates to YIQ coordinates.
colorsys.yiq_to_rgb(y, i, q): Convert the color from YIQ coordinates to RGB coordinates.
colorsys.rgb_to_hls(r, g, b): Convert the color from RGB coordinates to HLS coordinates.
colorsys.hls_to_rgb(h, l, s): Convert the color from HLS coordinates to RGB coordinates.
colorsys.rgb_to_hsv(r, g, b): Convert the color from RGB coordinates to HSV coordinates.
colorsys.hsv_to_rgb(h, s, v): Convert the color from HSV coordinates to RGB coordinates.

Example:

>>> import colorsys
>>> colorsys.rgb_to_hsv(0.2, 0.4, 0.4)
(0.5, 0.5, 0.4)
>>>colorsys.hsv_to_rgb(0.5, 0.5, 0.4)
(0.2, 0.4, 0.4)
>>>
