Each of the answers from the past two months can follow a different color of the rainbow to make a phrase. These are:
Red VELVET
Orange JUICE
Yellow SUBMARINE
Green LANTERN
Blue JAY
Indigo BUNTING
Purple HEART
After realizing this, all that remains is using the numbers in the blank rainbow to index into each of the answers (The 4th letter of VELVET, the 3rd letter of JUICE, etc.). This gives a final meta answer of VIBRANT.
