Trackmaster Revolution (TMR) New releases

I also like the look of the green paint than the black. Does the green color have a significance?

Briefly, it was originally LNER Apple Green, then black during WW2 (as with most other British locos). With nationalisation, it got the darker BR Brunswick Green scheme. After that in York National Railway Museum in wartime black again, and now still wearing flat black but due to be repainted LNER green sometime soon, I believe.
