GWR loco green 1906–1947
(rgb 1,46,3; hex: #012E03)
(rgb 1,54,2; hex: #013602)
Middle Chrome Green was adopted as the standard basic loco body colour around the turn of the century (some sources say 1894, others 1906).
It replaced various earlier shades of green, including the holly green applied at Swindon works, as well as the dark, bluish shade applied at Wolverhampton until at least 1894.
At some time during 1928, the Middle Chrome Green changed to a lighter, slightly more olive shade. This colour lasted until nationalisation.
The difference between the two shades is quite apparant when two models in the respective colours are seen next to each other. The earlier shade appears much richer, and enhances the lining considerably.
The colour panels adjacent are based on J.N.Slinn 'Great Western Way', HMRS 1978. Colour values in rgb and hex are given, but should be regarded only as a guide.
Commercial paints favoured by some modelmakers are Precision Paints GWR Green for the pre-1928 shade, and BS.224 Deep Bronze Green and Halfords Rover Brooklands Green for the post-1928 shade. It is always wise to check though, particularly with commercial spray cans, that the colour of the contents of the can match what is given on the cap.
