What color will sell easier? 73 Sport

Long story short. Looked for awhile for a 73 Sport to recreate my old high school car. Found 1 solid 73 so I bought it. Soon after I found a good solid 74 so I bought it also. I have built the 74 to look like my old 73 from school. Made it look like a 73 with 73 bumpers. I will keep it because it has PS, PB and air. Pretty much through with it.
Now what to do with the 73 that is a 318 no PB, PS or air. Very good solid car with a good running engine in it.
I have a couple weeks off for the holidays and would like to do the body work and get at least the outside painted. But what color? I will be looking to sale this one so I am thinking of changing the factory color. Is a factory K6 Bronze Poly. Not the prettiest color. I like it but probably will be harder to sale. So I am thinking to paint it either E5 Ralley Red or B3 Blue Streak ( Petty Blue). It will have a black and white interior with a white over the roof stripe.
So What do y'all think? Keep it the factory color or change it? What ever color I chose it will have the black hood treatment and hood scoop with out the half roof.
Bronze Poly

Petty Blue

Rallye red.
