you forget 1 very important thing Luke... most ute teams are cheap, so they use the basic colours

It's pretty much only a handful that have odd colours if you look at the field. majority that have fancy colour, are usually small bits, doable with decals. if this was just a few accent pieces in this colour, i would do them as decals.
Example, Kris Walton's Rentco ute... the fluro was eventually matched with PS fluoro's, after comparing a sample of each vinyl.
This has been the most difficult to match so far... i really thought TS-23 looked right, can lid matches pretty close but when dry, not even 5 shades close.
meh... live and learn and find another way to move forward
