Kona Paint
 

Where can you buy or color match paint for touch ups?

I have a kona nunu..blue

Not an easy job, but maybe if you go to BnQ, they do a colour match where you bring in a sample of the colour, they do some stuff on their pc and it gives you the same colour.
Good luck.
Sorry that company is in the UK so if you're not in the UK, the above won't help sorry.
