Car liveries depend highly on title sponsors and tradition . For instance Ferrari's red theme is beyond dispute . Possibly Lotus will continue in black , Mercedes in silver , Mc Laren in silver/red , team Caterham in green and Red bull in blue . Marussia will likely keep the red/black appearence . On the contrary i put a questionmark on the following teams liveries
Sauber - still keeps the basic white livey introduced since BMW days but gains more color year by year
Toro Rosso - probably deep blue with another new concept on the Red Bull logo
Williams due to ownership transition
However i miss a yellow car like old days Jordan with a snake/bee/shark on the nose tip .
