The RAL system allows for a whopping 10% color difference so be careful....
It looks way too green indeed....such a shame after their hard work.
Today I'm going to have my Ms. PAC decals scanned and paint mixed. Hope for better results...
I might get 2-3 of the smallest RAL paint pots just to make tests a see for the base. I mean, it cannot be any worse. How did the Ms Pac-Man mix go?
Looks like you need to go to Bruno's shop after all... the results there are good as we al have seen on the various posts..
Yes, if a solution cannot be found, I will go to Messancy. But the guys tried so hard they deserve a second chance. If they cannot manage then I'll change.
I have to do this job too...
Even if I don't want to repaint all sides, there are some holes
both on the right ad on the left sides...
I hope to find a similar color 
anyway most important issue is the glass, please let me know if dimensions you gave me are right 

The thing is that for touch-ups the paint just mixed would have been perfect. It is, to the eye at least, exactly the color of the rest of the cab, after being exposed to dirt, light and humidity for 30 years. It has a green touch to it which you do sometimes see on Baby Pacs that sell on ebay. The color under the decals is
very different from the rest. Much more vibrant and warm yellow.
The glass is arriving in 1 week, so I'll tell you if it's ok or not, and make pictures. Final width is 5mm they said. I forgot to ask for "without reflection", so I hope it does not mirror too much. We'll see. Price of the tempered glass made to measure: 40€ (for info, tempered glass is not cut to measure, but actually made to measure).
