 A three element color in the order of Blue, Green, and then Red.  Used only with DotStar methods.
 
 ## DotStarLbgrFeature
-Similar to the DotStarBgrFeature, except that it exposes the DotStar feature of a "luminance" value of 0-31.  This will require the use of the RgbwColor object and the W element must be set to provide a luminance override on the pixel.

+NOTE:  Use of any luminance other than 31 will cause the update rate on the LEDs to lowered, and thus not useful for POV displays.
