+# Kaleidoscope-LEDEffect-SolidColor
+
+This plugin provides tools to build LED effects that set the entire keyboard to
+a single color. For show, and for backlighting purposes.
+
+## Using the extension
+
+To use the plugin, include the header, declare an effect using the
+`kaleidoscope::plugin::LEDSolidColor` class, and tell the firmware to use the
+new effect:
+
+```c++
+#include <Kaleidoscope-LEDEffect-SolidColor.h>
+
+static kaleidoscope::plugin::LEDSolidColor solidRed(160, 0, 0);
+
+KALEIDOSCOPE_INIT_PLUGINS(LEDControl, solidRed);
+
+void setup() {
+  Kaleidoscope.setup();
+}
+```
+
+## Dependencies
+
+* [Kaleidoscope-LEDControl](LEDControl.md)
+
+## Upgrading
+
+Previous versions of `LEDEffect-SolidColor` used `kaleidoscope::LEDSolidColor`
+as a class for defining solid-color effects. This is called
+`kaleidoscope::plugin::LEDSolidColor` now. The old name still works, but is
+deprecated, and will be removed by 2019-01-14.
