+HsbColor represents a color object that is represented by Hue, Saturation, Brightness component values.  The primary use of this class is for easy definitions of color.
+
+## Properties
+There are three properties that represent the component values Hue, Saturation, and Brightness.  The values range from 0.0f to 1.0f.  
+H is the primary color component and represents a color wheel.  Often you will see examples of this being between 0 and 360, but this library it is between 0.0f and 1.0f inclusive.
+
+```
+float H;
+float S;
+float B;
+```
+## Constructors
+
+### HsbColor(float h, float s, float b) :
+Constructs a HsbColor using Hue, Saturation, and Brightness color component values.
+
+### HsbColor(RgbColor color);
+Construct a HsbColor using RgbColor, converting the Rgb to Hsb
+
+### HsbColor()
+Construct a HsbColor that will have its values set in latter operations.  
+CAUTION:  The H,S,B members are not initialized and may not be consistent until set.
+
+## Methods
+### static HsbColor LinearBlend(HsbColor left, HsbColor right, float progress);
+This will blend between two colors by the amount defined by the progress variable.  
+left - the color to start the blend at.  
+right - the color to end the blend at.  
+progress - (0.0f - 1.0f) value where 0.0f will return left and 1.0f will return right and a value between will blend the color weighted linearly between them.  
+This is a static function, which means you need to call it scoped to the object class and not an instance like...
+```
+    HsbColor results = HsbColor::LinearBlend(HsbColor(0.88f,1.0f,1.0f), HsbColor(0.12f,1.0f,1.0f), 0.33f);
+```
