It seems stupid, and it may be something that we'll get used to, but the Riot Points Icon and the IP Icon are the same colour in the store.
In the "legacy" client the RP icon was outlined in red, but in the new client, it's grey.
I've already accidentally purchased a summoner icon thinking it was purchasable by IP when in fact it was purchasable by RP (I was tired, clicking quick, and not paying attention).
Might be a good idea to maintain consistency on the colour of the icon from legacy to new client. I'm sure I won't be the only one to make that mistake :)
