For colours like that... no, not normally. However, I've tested the Astons quite extensively, and yes, the colours shared between models are always the same (Malham, Grasmere, etc).
Odd ones are things like Rosso Alfa since there's a few small differences; I've found 3, so far, but only two slightly different on-body colours (the third variation has a different colour chip in the menu, if that makes sense). Makes that have some old cars and then new models with the same vague name (Chevy and "Black") also might have a tiny difference between them. The other big ones are Toyota's vague names.
For 95% of the same-name chips available on multiple cars in the game, it's not strictly necessary to know which exact model it came from. And unfortunately, unless you own a copy of each of the, let's say, Blue Mica Metallics available from Toyota, you can't be 100% sure which version you've got with your login bonus. This is more or less to aid traders, and for some of us to keep track of what we're on the lookout for, or have stock of in our different accounts (I keep my secondary more or less as a paint-supply shop, now
).
Messiah - What do you mean, exactly? For thoroughness, I've listed
every chip in the game, so that people know all the ways to hunt down a particular colour if they are looking for it. For the Ferraris, I believe if you buy two models with the same paint job, the game will count them as different, but try previewing them in the paint shop and you'll see they're the same. The main goal actually was to track down which paints could
only be obtained through the login bonuses and 1000 tickets... but update 1.06 finally fixed the UCD and made multiple colours available
.
Personally, I tend to keep track of my paint chips just by selecting the most direct route. Say, for Mazda's Brilliant Black, my stock is all recorded under the Roadster RS (NC) '07, because it is the cheapest of the most readily-available ways of grabbing more.
