Touch up paint for diamond dark green kz900

I have some paintchip on my 1976kz900  diamond dark green. I tried the search function and found that kawasaki made a touchup paint for it ,but guess that is not possible to find.Is there a car or bike color that has a good match? I know the paint is a 3 step paintjob with silver under green tinted clearcoat . I can mix this color and use a airbrush painting silver and green clear over that ,but the problem is that the paint i use is acrylick made for modelkits se picks and i dont know if i can use the spraymax 2k clear on top of the acrylick paint.Another question: i have notised the sidecovers have some orangepeel mostly where the kz900 emblem is placed. Was this how the paint sometimes came from factory? if notim thinking of wetsand and buff out the orangepeel ,but there is a great risk since i dont know how thick the clear is and also maybe it is a tinted clear  that vould mess up the color totally.

There are no codes from Kawasaki, There is a company in the UK that supplies paints to original specs albeit they are now water based. RS Bikes paints.

They do touch up pots and will post globally. 
There is probably a similar company in the USA if your that side of the pond. 

Ok thanks i will check it out .Im based in Norway by the way i will update my user profile. I once had a car that was painted boston green metallick that i think is close but when comparing it side by side to the kawasaki it may bee way  off .
