Text color in shop when discount item

When there is a discount item, say a champion and you don't have enough IP to buy it using that method. If that champion is discounted at 50% and you have enough IP if the IP value was 50% off; the IP cost value will be white text instead of red. This implies that you can buy that champ with IP but you can't actually because the 50% discount only applies to the RP value.
