That's perfect! Thanks
Warning: Although the paint reference is good, you should know a few things and perhaps you do already. But it might be worth mentioning anyway.
The ideal for paint blending is that the stock used to produce a certain color remains exactly the same over the years and the guy mixing paint in Los Angeles in 1999 does it exactly the same way using exactly the same basic materials as does the guy in Dubai this year. That's the goal, but it may not match reality for obvious reasons. And now, with water paints all the rage, Rosso Corso can mean several things. You have to dig deeper for the whole truth.
But what is guaranteed to be not quite correct are the photographs of cars shown in the reference color guide. Modern digital cameras are pretty decent at guessing the "color temperature" of a scene, but they are FAR from perfect. Without a high end camera and without carefully calibrating the scene with a known color reference card, the exact color of a scene can be rather far from reality. Then, when you post to the WEB, colors can be even further from the real-world truth. Not only can't you reliably pick your favorite color from the photographs of the cars, you can't even reliably compare one red to another red. Plus, if every photo is taken with a different camera on a different day, then who knows what's real?
In other words, the saturated red looking version of Rosso Corsa on one car photo may actually be slightly maroon in real life.
So, while this guide is very nice and this guide is far from useless, it should be used with some knowledge of the potential pitfalls.
