Case DC paint

I'm attempting to repaint my Grandfather's Case DC.
My understanding is that Flambeau Red is the color it's supposed to be.
However, after power washing it, it shows a much lighter shade of orange.
I have already painted some of the easily removable parts with Majic's "Case Orange" as it closely matches the color that is on most of the tractor already. I attached a photo that shows what I have now.
The hood and grille are what I have painted in the "Case Orange", while the radiator surround, steering arm, rear fenders and rims are in what I believe my Grandfather has repainted in the past, Flambeau Red. Also note that the steering knuckle, oil pan covers and the majority of the rest of the tractor are in what I believe to be the original color - this lighter orange.

I guess what my question is, do I repaint it in Flambeau Red, as I'm told it's supposed to be, or do I try to match what the tractor appears to have originally been and continue with the "Case Orange" that I have started? The paint that my Grandfather has done does not really match what I feel this tractor should be.

This second image shows what the hood looked like before I painted it, I'm assuming it's Flambeau Red, while the side of the engine is in the original color.

I personally like to paint a tractor back to the color it was when it left the factory but I was never given a tractor to have any sentimental attachment to. I think in your case I would be more incline to restore the tractor to the appearance your grandfather made it. Chances are the color was only altered because the color he used was easier or cheaper to use and it was just to prevent rust anyway but there is no way to know that. If you do want it back to the original color, the whole tractor with the exception of the wheel rims were flambeau red. The wheels were not painted but galvanized. Most restorers I think just paint the wheels with aluminum paint.

i would paint it the same as the hood looks pretty
close to me.
