I tested every humbrol green colour back when I did this helmet, and the 'chameleon green' mix was significantly different to humbrol uniform green (#76 from memory). That's not to say that uniform green isn't a different mix these days, or that you didn't indeed get a good result with it. It can also be vastly different comparing photos to real life colour tests. Hopefully you've been able to test in person, and found it super similar. That would be a great result. But at least back then, nothing in a tin really came close to the mix I concocted
