This one was (mostly) white originally. At 1978, it's too late, technically, to actually BE this colour.
But who cares? The owner likes it this way and the Magenta will probably have advanced it's value in some peoples eyes!
But please don't underestimate the amount of work involved in doing it properly, the car above was stripped to a bare shell to paint, no glass, wiring, pipework or interior fittings, the vinyl roof and headlining were all removed too. Even the back axle and front subframe were taken out and "slave" units installed to keep it mobile during the painting process. It saves money on masking tape true, but that's the ONLY cheap bit!
I do appreciate the quandary, i'm not a fan of Russet myself and my own car is on it's way from Russet to Vermillion for a variety of reasons. But like most things of this nature, there are a million reasons for buying a particular car, the supply of good ones is finite and the condition of the body and relative price are MUCH more important than what colour it is! Beggars can't be choosers or something like that.
Buy a brown car if it's the best one you can find, drive it around a bit and see if you can live with it (you can't see much brown from inside) If you can't, hopefully there will be enough contingency in your budget to paint it a colour you DO like. Budget includes TIME as well as money, a good job is not quick!
Of course, if you are starting with a restoration project, it's much easier to choose a different colour and make it practical to do it, as most of the stripping out will need to be done anyway!
