29 inch balance from hurricane impact window

Thanks for posting. Good question. Generally, if a spiral balance has a yellow tip, it will be really yellow. Anything else, with a hint of red, is probably just a faded red tip. So for a 5/8" S600-29 Spiral Balance, the correct choice is most likely a red tip option, which will support a sash in the weight range of  7 through 29 pounds. If you want to be safe of course, you can always weigh the window sash the spiral balances support to confirm. Let us know if you have further questions.
