You can use the BitConverter class to get the bytes from the int:

byte[] values = BitConverter.GetBytes(number);
if (!BitConverter.IsLittleEndian) Array.Reverse(values);

The array will have four bytes. The first three bytes contain your number:

byte b = values[0];
byte g = values[1];
byte r = values[2];
