/**
 * Model object that represents a Color Property that the developer can subscribe to changes for
 * to update specified views.
 *
 * Example:
 *
 *  Say you have a {@link Topping} that represents a PRIMARY color that you want to use for toolbars, fabs, and the like.
 *  and you want to update this color using Palette based on primary images loading (such as a banner) and you want bound
 *  views to automatically react to these changes. The user would then bind the associated views to this property
 *  and Scoops will automatically take care of it
