The colors Red and Blue are prominent in this episode.
Red is said to represent many things; from blood, to love, to infatuation. Red can symbolize excitement, energy, speed, strength, danger, passion, and aggression. It is also looked upon as a sensual color, and can be associated with man's most profound urges and impulses. Examples: Rob giving Sasha the red rose, and Jamie's room, which is painted red.
Blue is the color associated with girls who have pure qualities. Blue also usually indicates femininity and life, also depression and sadness. Example: Sasha's room is blue (and for that matter, Sooz's room is too).
