 ## Methods
 ### uint8_t CalculateBrightness();
 CalculateBrightness will calculate the overall brightness.  
-NOTE: For color objects with only W set, it will return W.  For color objects with W set to zero this is a simple linear brightness.  For color objects with values in W and another color component, the overall brightness is an equal mix of the color components and the W.

 ### void Darken(uint8_t delta);
