You are right, today the quality of the car will outweigh the colour on cars this old. As I said if the right combination came up in the right condition in green i'd buy it, but i'd still hold back on price a fraction. And if it needed paint i'd do it another colour. HQ probably Orchid or Saffron. HJ probably Satin Mist or Absinth or even Sepia, HX maybe Royal Plum and HZ maybe Ultra Blue.
