 * \brief Color10 Click example
 * 
 * # Description
 * Color 10 Click is carrying a sensor for RGB and IR light sensing as well as 
 * the RGB diode incorporated on the board which makes it good color detection 
 * device when its combined with a white LED.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initialize I2C driver.
 * 
 * ## Application Task  
 * This example senses orange, red, pink, purple, blue, cyan, green or yellow color
 * and IR light and print it via UART terminal.
