WebApp problem

http://pendulum.offroadagency.com/

drag it.. I have made this app but when i apply colors to the balls its speed goes up automatically...and graphics goes bad..

.I am applying color through renderer.material.color=color.red; like in unity everything works clearly and quality of the pendulum is great but when i run it in web player it quality goes bad like you can see my quality settings of web player are at its highest level.. functionality of the app is perfectly fine when you drag it it rotate i am just worried about the quality and its speeding up..
