# LED-ActiveLayerColor A simple way to light up the keyboard in uniform colors, depending on what layer one's on. Unlike [Colormap](Colormap.md), all keys will be the same color. But this plugin uses considerably less resources, and is easier to set up as well. A perfect solution when one wants to quickly see what layer they're on, with minimal resources and time investment. ## Using the plugin To use the plugin, one needs to include the header, and activate the effect. Then, one needs to configure a color map: ```c++ #include <Kaleidoscope.h> #include <Kaleidoscope-LEDControl.h> #include <Kaleidoscope-LED-ActiveLayerColor.h> KALEIDOSCOPE_INIT_PLUGINS(LEDControl, LEDActiveLayerColorEffect); void setup () { static const cRGB layerColormap[] PROGMEM = { CRGB(128, 0, 0), CRGB(0, 128, 0) }; Kaleidoscope.setup(); LEDActiveLayerColorEffect.setColormap(layerColormap); } ``` ## Plugin properties The plugin provides the `LEDActiveLayerColorEffect` object, which has the following method: ### `.setColormap(colormap)` > Sets the colormap to the supplied map. Each element of the map should be a > `cRGB` color, and the array must have the same amount of items as there are > layers. The map should reside in PROGMEM. ## Dependencies * [Kaleidoscope-LEDControl](LEDControl.md) ## Further reading Starting from the [example][plugin:example] is the recommended way of getting started with the plugin.
