To be fair to Caterham, Group Lotus sponsored Renault F1 under a JPS-style livery (gold and black) but sponsored ART (and KV Racing in IndyCar) in Team Lotus’ green and yellow. The naming war had already started and I felt Group Lotus was “stealing” Lotus’ livery to challenge them. But as Caterham had started the season in an AirAsia livery, they worsened the situation by using “their” livery. I saw it like ART copied Lotus’ livery before they actually had it.
Now, with the dispute settled, I believe the agreement included a part regarding liveries – Caterham yellow & green, Lotus black & gold.
