The color projection system also includes a projection lens optically coupled to the polarizer. The aqueous formulation of leleshwa is used alone as a rinse to treat hair or combined with other ingredients to form hair treatment compositions that include rinses, conditioners, shampoos and combinations thereof. The support post is adapted to receive the guardrail such that the rail face of the guardrail runs generally perpendicular to the strong direction such that the support post resists an impact on the rail face of the guardrail and yields to an impact force on the end of the guardrail.
