Example color logic using 4 keys, 4 tweens, totalColors 16
totalColors including Bizarro colors is 30
finding color 14 :
    Key Colors : 00 __ __ __ __ 05 __ __ __ __ 10 __ __ __ __ 15 
Actual Colors : 00 01 02 03 04 05 06 07 08 09 10 11 12 13 14 15
Bizarro Colors : 29 28 27 26 25 24 23 22 21 20 19 18 17 16
14 / Tweens+1 = 2.8
Guessing color 14 is between keys 2 and 3
determining which key colors 14 falls between..
checking if 14 falls between key 0 and 1
checking if 14 falls between key 1 and 2
checking if 14 falls between key 2 and 3 : BINGO
color is a tween between (79,255,184) and (18,255,250)
diff per tween is -12.2,0,13.2

COLOR IS (30,255,237)
