For some reason, I am not able to create this color in cycles…Can anyone help me? I got frustrated and trashed my file
I can’t create the color, a greenish glow in the dark
Something like this?
That’s easy. Plug some noise into a color ramp and then the color output into an Emission shader…
What else? The blend file, maybe?

Here it is. Enjoy! 
Thanks! I was actually looking for just node node setup for the color, but this definitely works. thanks a lot 
by “color” I meant the soft glowing green, somewhere between the brightest and darkest colors, but still, I an use this
If you’re still trying to get the exact colour, then change one of the windows to the UV/image editor and load your reference image into it. When you choose the colour in the node, use the colour pick tool (the icon looks like an eye dropper), go over to the UV/image editor, click the colour you want from the image, and there you go. (:
I use this method all the time for texture painting, it is infinitely useful.
