I'll be sticking with the orange just because I can't be bothered to edit my website. Besides, I'd say the colour is pretty flexible anyway.
CoinDesk, for example, use more of a yellow variant and it's not like anyone cares.
i agree, bitpay, coinbase, bitstamp, kraken should be the people pushing for advertising. as for the logo..
even visa tries to change its logo

so try making something new and then send it to the main bitcoin service companies and give them the freedom to use the logo in all there advertising... but make sure its good, better then previous versions otherwise it will just get ignored.
I think they've changed it again since that one. There's no yellow at all in the logo on my latest card.
