Hi Gryphonknight,
You may have gotten your answer already - but here is a summary:
The tan is the exp of a different color hero fed to another hero.
The Diff Color and Same Color are the total number of respective heros needed to reach the 353,559 exp for a 5 Star from Level 1.1 to 4.80.
The Red 22M, 8.6M and 5.3M are pretty sound estimates of the food required for each hero.
