 * \brief Color8 Click example
 * 
 * # Description
 * This demo app reads RED, GREEEN, BLUE, IR data and return detect color.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initialization device device configuration for start measurement.
 * 
 * ## Application Task  
 * Reads RED, GREEEN, BLUE and IR data. 
 * Converts data to HSL value and return detect color.
 * For a successful color test, place a click near the color of the monitor and detect the color on the screen.
