The LED Animation library has a color module to make assigning LED colors much simpler. In this module, the RGB value for a color is assigned to a color name variable. In your code, simply import the colors you'd like to use from the module, such as RED or BLUE, and then use them anywhere you would use an RGB tuple, e.g. (r, g, b).

Available Colors

The current complete list of colors can be found in the color module documentation. Available colors include:

  • RED
  • YELLOW
  • ORANGE
  • GREEN
  • TEAL
  • CYAN
  • BLUE
  • PURPLE
  • MAGENTA
  • WHITE
  • BLACK
  • GOLD
  • PINK
  • AQUA
  • JADE
  • AMBER
  • OLD_LACE

To see the RGB value for each color name, check the documentation.

Usage

Using the colors with the LED Animation library is easy. Simply import the colors you want to use, and then include them anywhere you would use an RGB value.

This example uses red.

import board

from adafruit_led_animation.color import RED

# Update to match the pin connected to your NeoPixels
pixel_pin = board.D6
# Update to match the number of NeoPixels you have connected
pixel_num = 32

pixels = neopixel.NeoPixel(pixel_pin, pixel_num, brightness=0.5, auto_write=False)

blink = Blink(pixels, speed=0.5, color=RED)

while True:
    blink.animate()

Included at the top is the following line:

from adafruit_led_animation.color import RED

Then, when the animation is set up, instead of using (255, 0, 0), you can use RED.

blink = Blink(pixels, speed=0.5, color=RED)

You can import more than one color at the same time as well. This example uses purple, amber and jade.

Included at the top is a similar import line, but this time, there are multiple color names, separated by commas.

from adafruit_led_animation.color import PURPLE, AMBER, JADE

Then each color is used in various places later in the code.

blink = Blink(pixels, speed=0.5, color=JADE)
comet = Comet(pixels, speed=0.01, color=PURPLE, tail_length=10, bounce=True)
chase = Chase(pixels, speed=0.1, size=3, spacing=6, color=AMBER)
Using these colors is not limited to use with the LED Animation library. They can be used anywhere you would otherwise use an RGB tuple value. Load the LED Animation library onto your CIRCUITPY drive, and you can import these colors into any code.
