After having trouble finding this on the internet, here are some colour codes that are "good enough" for me to create some fake screenshots from the Commodore 64.
If you google around you will find some in detail discussions how the color management works on the Commodore 64, but for my purpose this was enough.
#000000  
#FFFFFF  
#744335  
#7CACBA  
#7B4890  
#64974F  
#403285  
#BFCD7A  
#7B5B2F  
#4f4500  
#a37265  
#505050  
#787878  
#a4d78e  
#786abd  
#9f9f9f
