# Kaleidoscope-LED-ActiveModColor

With this plugin, any active modifier on the keyboard will have the LED under it
highlighted. No matter how the modifier got activated (a key press, a macro,
anything else), the coloring will apply. Layer keys, be them layer toggles,
momentary switches, or one-shot layer keys count as modifiers as far as the
plugin is concerned.
## Using the plugin
To use the plugin, one needs to include the header, and activate the effect. It
is also possible to use a custom color instead of the white default.
```c++
#include <Kaleidoscope.h>
#include <Kaleidoscope-LEDControl.h>
#include <Kaleidoscope-LED-ActiveModColor.h>
KALEIDOSCOPE_INIT_PLUGINS(LEDControl,
ActiveModColorEffect);
void setup () {
Kaleidoscope.setup ();
ActiveModColorEffect.highlight_color = CRGB(0x00, 0xff, 0xff);
}
```
It is recommended to place the activation (the `Kaleidoscope.use` call) of the
plugin last, so that it can reliably override any other plugins that may work
with the LEDs, and apply the highlight over those.
## Plugin properties
The plugin provides the `ActiveModColorEffect` object, which has the following
property:
### `.highlight_color`
> The color to use for highlighting the modifiers. Defaults to a white color.
### `.sticky_color`
> The color to use for highlighting one-shot modifiers when they are sticky. Defaults to a red color.
