I think I have read that the colour pre and post war was different and this site certainly lists two shades. **LINK**

I would also think that the shade might change depending upon where it was painted and with service.

I have think Malachite green was used on southern region and GWR was middle chrome green

Bradley (Locomotives of the LSWR Vol 2) lists which of these locomotives were painted unlined dark green or unlined light green in 1940-41. I assume these are the two shades of malachite as these are changes from Maunsell lined olive green.

I assume from the picture on Reeve's website that your locomotive is in the 823-847 series. If you are building 841 herself, Bradley says she went from Maunsell livery to dark green with "Sunshine" lettering, and was like all the class repainted in unlined black after nationalisation.
