just in the nature of digital cameras (white balance) and screen rendition/ calibration, I would NOT go by a picture for something you're wanting to match.
From here (screen is calibrated, but I can't speak for your camera) it looks like it would match the darker/ more luminescent HCR green, but not the green that would be on an M.
The difference in how your camera can produce color in different lights though, can be huge, I'd try to find a way to get a sample, or find someone nearby who can help. (if it's a customer you care about that is!)
(edit: just went to look at the HCR closer, that color (yours) is deeper & lighter in tone than the HCR also.
