Paint Question: Should I...

New to this great forum and to a Dodge Dart and was wondering if I should keep my new 1965 Dart GT 225 Convertible the original color(Gold Metallic) or change it to a new one(Bright Red)? The color is not the most attractive color and it has been repainted the same color(Gold Metallic)... Does it really kill the value if I change the color? I have have the original engine, but currently have a 69 225 slant 6 in it.... Thanks everyone for all your help!!! Here is my car below...
