Color KZ440ltd ?

Hi,
I'm a new member and found this very informative Forum while I was searching for a color code for a KZ440ltd licensed in May 1982 in Germany. I'm 52 and own by myself a Z1300 A2 and two CBX1000. I'm an automotive Engineer and from time to time I rstore old bikes. Now a friend of mine asked me to help him repainting his wifes bike. A KZ440ltd. All I find is a somhow black paint version with two red stripes. This bike is in one hand since new and never repainted. And it is definitely not black. As you can see in the pictures it is somehow a dark metallic red or purple. I think the color Luminous Midnight Red comes close or is the right one. Is here anybody who could give me advice or confirm my research?
Many thanks in advance
Karl
