The color is a flourescent orange. The X-6 isn't going to be close. Hiroboy does make a flourescent orange but I don't know how close it is to the color used on the Mazda. You might try MR Color if you can get that. I bought a bottle of thier flourescent orange for the tail piece of the Fujimi GSXR I'm working on. It is similar to the Tamiya TS-31.

It looks like Tamiya sprays are available again in the UK. Hiroboy has a poll on his site asking if he should start carrying them. You might see if he can order you what you need.
