Beige is available any time but the perfect red might not come along again for a long time. But it also depends on which color you'd get the most out of.
I adore gold hardware but 12a red is irresistible too :S beige is easier to match with outfits however red will stand out and like a lot of people mentioned 12a red was so popular it sold out really quickly I'd hate to make the choice but good luck
