I agree with Christopher.
Real Carmen Red is surprisingly more 'brickish' (orange) than you might imagine. And in many ways, although a Carmen Red E-type is about as close to my definition of 'the definitive article' as you can imagine, viewed in the flesh the colour is actually a little 'odd' especially if you have it in your mind that it's going to 'zing' - perhaps along the lines of a Humbrol red or a full-blooded Italian
rosso corsa.
To prove a point, here's a rare period colour photo, c.1967, of me with my original E-type (ok, my Dad's): all together now, 1-2-3,
ahhhhhhh.......
OK, it's a Polaroid, and therefore it introduces colour bias of its own - especially given that it's almost 55 years old, compounded by being played back through your computer monitor or phone screen - but you can definitely see what Christopher means about the distinctly orange hue.
Actually although Polaroid introduces bias, it's probably not too bad for this particular colour. I think part of the problem is that most people's perception of how they imagine Carmen Red to be is driven by having seen it in colour photos, and most film emulsions at the time, and even today's digital capture, tends to push orange to red, and red to dark red. Hence photos of Carmen Red cars tend to look much more 'red' than was actually ever the case. As an aside, this shift in hue was deliberately exploited by McLaren in the Marlboro era, with their distinctive 'red and white' cars actually being vivid fluorescent orange ('Rocket Red') and white. McLaren had spotted that if they wanted their red to appear red on TV and in print, they were actually better off starting from a different place - a fact that came as quite a surprise to most spectators the first time they encountered one of their cars 'live' at a race.
