That is the colour, I am sure you can get local trade paint mixers to make up a batch

I'll pm you with a picture as I can't post in a comment here

Thanks, Richard. The first couple of examples I found on searching didn't look at all green!

This is an interesting observation: in very small areas the color is not at all green, but the larger the sample, the greener it appears to become.

My use of this, or a similar hue, will be restricted to a panel about 20cm (8") deep along the front of the four modules. It will be painted on smooth hardboard and will have a dull finish. It will be fixed to the modules with brass screws in screw cups.

In addition, I have also got to think about where to place the control panel for the Tortoise motors, interior lights, etc. I will be using a Bachmann Dynamis DCC controller for the actual trains, which is hand held.
