Spiral balance color

A home owner from California, USA says:
I am replacing old spiral balances on my vinyl tilt windows. The old balances are 3/8" 29" long and green tip, however my window only weighs 12lbs. Should the replacement balance be a red tip? I'm afraid that the window would be too light for the green tip balance. What weight range is the red and green?

Tom from SWISCO responded:

Hello! If your sash is only 12 pounds then the green tip would be a little too strong, yes. You can actually see a chart on our S900-29 store page that tells you how much weight each option supports: Red carries 10 through 22 pounds while Green carries 14 through 26. In your case, red would be my recommendation.
