Hi Allan,
I don't think matching the colour on a computer will work ,the image comes out
a different green depending on background lighting.
I took two images one after the other and got two different shades of green,
what I did find is a Light Green glass deco paint pen is a great match
for the green cowl.
If you paint the green on over the black cowl it will come out a different colour,
you may need a spray putty primer first then grey primer on top of the spray
putty primer then the green.I only mention those steps because if I don't
paint that way the paint is easily scratched off.
The glass deco paint pen is only a good colour match when it is still wet in
the pen,when it dries out it turns a dark green, so if you can find one or put up
a wanted ad for the green pen to colour match at a paint shop it should be a good
match if the inside of the cowl I photographed has not faded.
In these links the cowl looks slightly different to the green they show on the computer.
