there are two gold colours used on the cb750 they are candy gold cq
sunny gold metallic dm
ignore the letters after the colours they are just part numbers HONDA use ,and are no help in matching the colours, unless you are buying new parts from them , i think the candy gold is the uk spec bike and is a darker shade and the sunny gold metallic is for the american market and has a more of a yellow tint ,if you have a side panel any good sprayer will match it up you will also need a silver basecoat and a lacquer topcoat i have resprayed two of my bikes candy blue green (one was more green and the other more blue )and one candy ruby red that i dont have a bike too compare it with ,but i bet it will be different shade ,candy colours are american paint and not cheap they also contain celolose so some painters wont go near them they are notoriously difficult too match too many coats and the shade gets darker by the way there is a lot of good two pack paint about now so dont be put off and have fun
