skittle sorter program "if then statement help"

i creating skittle sorting machine school , having trouble completing program.

i new arduino, shouldn't overly difficult.

i using following program sense colors... , works.

my question how implement "if then" statement 'if colors within range, call color, , move servo location".

code: [select]


#include <wire.h>
#include "sfe_isl29125.h"

// declare sensor object
sfe_isl29125 rgb_sensor;

void setup()
{
 // initialize serial communication
 serial.begin(115200);

 // initialize isl29125 simple configuration starts sampling
 if (rgb_sensor.init())
 {
   serial.println("sensor initialization successful\n\r");
 }
}

// read sensor values each color , print them serial monitor
void loop()
{
 // read sensor values (16 bit integers)
 unsigned int red = rgb_sensor.readred();
 unsigned int green = rgb_sensor.readgreen();
 unsigned int blue = rgb_sensor.readblue();
 
 // print out readings, change hex dec if prefer decimal output
 serial.print("red: "); serial.println(red,dec);
 serial.print("green: "); serial.println(green,dec);
 serial.print("blue: "); serial.println(blue,dec);
 serial.println();
 delay(2000);
}
