Coding Badly,
I looked into the comma operator, but I'm not sure how I can use that to my benefit for assigning one color to each band.
I'd like to assign the colors like the following:
I decided I am going to stick with the r,g,b values for my map spectrum. It just works better. I want to add another case for assigning one color per band, but I can't figure this out with modifying my mapSpectrum(). Is there any way to do it? 
See current code below:
#include <MSGEQ7.h>
#include <Adafruit_NeoPixel.h>
#define pinReset 27
#define pinStrobe 26
#define BRIGHTNESS 65
#define LEDs 280 //total number of LEDs
#define PIN 22
#define BUTTON_PIN 28
#define OffColor 0x000000 // OFF
