on the other hand mclaren has been silver since the late 90s, right when they switched from marlboro to west. i think their philosophy behind this livery is that mclaren is silver and black, and the red is from honda altho they should've written honda with red then aswel. don't forget that all the promotional slogans basicly said they're not going to repeat history, but to make it. whatever the making part means.
yes mercedes color is silver too.
i guess it's just a case of haters gonna hate then.
EDIT: oh and before any of you will start with this "true mclaren colors" or "true to their past" crap. let me just remind you that the only real mclaren color was the mclaren orange which was last used in 1973! since then they've had the colors of their main sponsors. from marlboro, to west, to vodaphone ect. but notice how after the west period they still kept the silver color. this was also around the time when ron started to really turn mclaren into a brand. so i think silver/chrome is the new mclaren color.
but at the end of the day, the livery doesn't make the car go any faster.
now let the flame war begin.
