Remember there were three paint schemes - the passenger ‘pine tree / butterknife’, the Loewy passenger, and the freight scheme.
The middle (very faded) pic is the pre-Loewy pine tree passenger scheme - dark green (almost brown) and light green. The light green “butter knife” matches where the light green was on the passenger cars - dark green on top, light green thru the windows, dark green below.
The lower pic is the Loewy scheme. That’s the scheme that used the “mignight evergreen” or however Loewy described it, not the freight scheme which had already been around for about 10 years before Loewy was brought in.
The top pic shows the freight scheme, black with dulux gold "pine tree’ with a dulux stripe along the bottom of the engine body.
