st3m.ui.colours module

Colour data is expressed in floats. r, g, b, v, s range from [0..1] and clamp beyond, h ranges from [0..math.tau] and overflows gracefully for values within [-100..100].

Example (note the asterisk expanding the returned tuple):

import leds
import math
from st3m.ui import colours
leds.set_all_rgba(*colours.hsv_to_rgb(math.tau*5/6, 1, 1), 0.5)
leds.update()

colours.hsv_to_rgb(h: float, s: float, v: float) → Tuple[r : float, g: float, b: float]

Returns RGB tuple corresponding to the HSV input parameters.

colours.rgb_to_hsv(r: float, g: float, b: float) → Tuple[h : float, s: float, v: float]

Returns HSV tuple corresponding to the RGB input parameters.

This module also provides some color constants:

colours.BLACK

colours.RED

colours.GREEN

colours.BLUE

colours.WHITE

colours.GREY

colours.GO_GREEN

colours.PUSH_RED
