I wrote this song in like a week (I was only able to work on it like 1-2 hours per day and I was usually stuck between doing homework and this) so it's gonna sound pretty bad and rushed. The three colors I used is Red, Pink, and Yellow, the lyrics of the song contribute to the colors, basically, the melody is the Red and Pink, as the melody is fast paced and exciting, the Pink for the protagonist's love to a girl (in the lyrics), and Yellow for the optimism.
