> [On Ladybug,] I had to adjust the colors slightly to match the header (and the bezel from Funspot).
As many of these games are now approaching 30-40 years old, something to keep in mind is that artwork fades over time.
It depends on the quality of the glass/plastic and paint used on the cabinet, and also on what type of lighting the cabinet might have been exposed to over all this time.
Flyers are almost always a good reference for original colors:
In this case... I'm gonna say that Funspot's artwork is faded after so many years.
This is something that I didn't consider way back in the beginning either, and I've had to go back more than a few times and correct stuff from back then (and there's probably still more).
I specifically remember Ladybug being one that I corrected. And after checking, it looks like Cheeky Mouse might need to be revisited also.
Something to keep in mind as you go forward with this.
RELAX and just have fun. Remember, it's all about the games.
