NO, No, No, to a black top tube. Take a scratch-x self degrading rubbing/polishing compound to the fork. A half interested clerk at an automotive paint store should get you to a match. Various paint choices, house of color, Chromabase (was Dupont) others. Many paint stores can even make up a custom rattle can of the mixed color, I would clean the fork and dab on the color mix onto the steerer to confirm. Buy a quart of Prepsol, used to remove any contamination and wax, oil to promote adhesion. A possible strategy would be to talk to a used car manager, they all have a mobile guy or two who touches up cars and knows tricks, has the materials to get you there. Might even come to your house.

A fellow club member decades ago had a Super this color and basically the same graphics, on his bike, All Black, no two tone on the chainstays. I Definitely assess the graphics as Original.

‘if you want to ruin a bunch of the resale value later, suffer a bout of paintitis and paint it black.
later today I can post some images of my earlier frame with All black graphics.
