Jay Car's corporate colours are blue and white. Mitsubishi electric's colours were not. Kia's logo was different on one of the Kiwi team's super rugby jerseys too.
I don't really care what the colours are myself - pulling major sponsors requires a lot of work over time to foster a relationship. Some clubs don't even have them, and we're getting upset over what was reported to be the richest jersey deal in NRL history (whether it was or not I don't know). I have no idea if we ever even discussed changing the logos colour or not, I just think there is a disproportionate discussion on what colour sponsors logos look like on our gear.
