larry-rgb is a plugin for larry that pics colors from your (background) image and smoothly transitions your LEDs from color to color.

Make sure you have machine running OpenRGB. This will typically be on the same machine that you'll be running larry on.

1. Install larry.

Install larry-rgb:

pip install git+https://github.com/enku/larry-rgb

2. Add larry_rgb to your list of larry plugins, e.g.:

   # ~/.config/larry.cfg
   
   [larry]
   ...
   plugins = gnome_shell vim larry_rgb
   

   In addition you can add configuration for the plugin:

   [plugins:larry_rgb]
   # address[:port] of OpenRGB server
   address = 127.0.0.1:6742
   
   # How many steps in the transition from color to color
   gradient_steps = 20
   
   # Maximum number of colors to get from the input image
   max_palette_size = 10
   
   # Time (in seconds) between color changes when fading
   interval = 0.05
   
   # Time (in seconds) to pause after fading from one color to the next
   pause_after_fade = 0.0
   

3. (Re)start larry and enjoy!
