Congratulations! To me it looks like a school bus here in the states. I like the lighter true bright yellow (like on my '57 Chevy). It is amazing how many shades of yellow on all the cars out there. It is truly an individuals opinion. It sounds as if it really appeals to you, so that is what counts the most.
This is my wife and I taking 4 laps around Texas Motor Speedway track in my bright yellow '57 Chevy.
Yeah, I would say that the green would definitely be preferable to the Sunflower. Some lime greens can look nice but I'm not sure if Electrolyte Green is in that category or not. Personally, I'm waiting for VW to come back with the "grey poupon" mustard color they had a few years ago.
