Original color?

[74 boler roller]

Hey everyone, proud new owner of a 74 boler here!
I originally thought our trailer was white gelcoat,covered in faded spray on box liner. I have been doing my best to remove the box liner, to restore the original white gelcoat, and prepping for some fibreglass repairs, and I noticed under the white, is green. Could anyone tell me if my boler is originally white, or green? Should I be sanding past the white to reveal the green underneath?

Im adding some pictures, hopefully someone can help me out!

Yes, that particular green is one of the original gelcoat colors. Typically the Boler 13's were colored (green, burnt sienna, blue, etc) below the belly band and white above the belly band.
