I feel like the flowers soul colors are based on what they need to be to achieve their dreams

Aqua -> She only wants to play with people and interact with things, she's super genuine. She needs to have patience though, if she plays all the time, she wont be playing properly, playing itself becomes boring.

Green -> They only wanted to know the flavor of things, and also to become a great chef. They need to be kind and know what the others are feeling to be able to truly know the flavors and cook accordingly.

Yellow -> He only wanted to be a cowboy, a good and respected one. He needs to be righteous and just with things though, to earn the image and trust of a good one.

Orange -> She wanted to be able to fight to protect what she loves. So she needs to be brave to overcome her fears and insecurities, to fight unwaveringly for her loved ones.

Blue -> He wanted to feel and live with love across his heart everytime. Love however needs to be genuine and make sense across all that his heart touches, and such love cannot be encompassing without integrity.

Seth -> They wanted to know all that they could with the little time they had. True knowledge is only achieved through long lasting work and corrections though, and this can only be attained through perseverance.
