The TriColor effect extension is a part of the LEDEffects library, not a stand-alone base library of its own. It is used to implement the effects in that library.
It is a class that can be used to create LED effects that all follow a similar pattern: alphas and similar in one color; modifiers, special keys, and half the function keys in another, and Esc in a third (this latter being optional). If we have a color scheme that follows this pattern, the TriColor extension can make it a lot easier to implement it.
Using the extension
Because the extension is part of the LEDEffects library, we need to include that header:
Then, we simply create a new instance of the TriColor class, with appropriate colors set for the constructor:
The first argument is the base color, the second is for modifiers and special keys, the last one is for the Esc key. If the last one is omitted, the extension will use the modifier color for it.
