Hi, I went to my local model airplane etc store and ended up buying a few colors of Testor's paint (small bottles) to get the right blend. For my situation it is an SLC and the red was a bit in the orange direction so I bought a close but darker red then tinted it with orange. After a few tries and layers it came ut pretty good to my eye. As far as getting a true Cervelo color I do not know of a source but if you search this forum there are references to some automotive colors but I could not find these and I needed to brush the paint on in my situation.
I hope this is some help.
