Theme: tropical, carnival, karibi
Solution: Since it is a carnival theme, tropical.. the girls at the carnival wear feather costumes. Also feathers are association with the tropical parrots.
Soar means "fly or rise high in the air" so the feather is again the logical solution.
The colors are as you requested, vibrant and in relation to colors of tropical birds and carnival costumes.
And the last but not least... the feathers are forming the letter S for Soar.
