Sir if you are going for darker shades then keep in mind , you'll need to spend more on the body work - the car needs a bit of restoration and preparation especially for dark colors , get some good bumpers and get the alignment done at first
The paint and its required stuff won't cost more than 5k but at times you have to pay 10x's the price of the paint alone to get the paint a worthy investment
An average paint job costs 25k-35k , a good paint job would cost 35k-45k if baked - its your budget and your car , spend wisely
I myself am a fan of ELECTRON PEARL BLUE B-95p honda
A good paint shop would give you the exact base for it aswell (they have all the codes worldwide) I repeat , don't expect the same results that you see in the pics posted above , those are done by professionals and the way they finish the paint is exceptional, hence the results
Just pay attention to the details , follow the recent threads on pakwheels and honda-tech so u can guide these local painters if you grasp better than them in a short time
Best of luck with your project
