Tru-Color Paint is a model paint manufacturer based in the US. They have an extensive line of railroad and car paints and they are continuously expanding their military line (aircraft, naval, armor).
This set includes the following colors (all of them already available in their line).
- TCP-1281: Dark Green
- TCP-1281: Dark Earth
- TCP-1284: Dark Sea Grey
- TCP-1287: Ocean Grey
- TCP-1288: Sky Type S
- TCP-1290: Interior Green
The set includes the main colors used by the RAF in the early years of WWII in Europe (Dark Green, Dark Earth, Sky, Interior Green) and some of the colors used in the later years (Dark Green, Ocean Grey, Interior Green). Including Dark Sea Grey is perhaps a bit unusual as that color was rarely used. Personally, I would have replaced it with Medium Sea Grey, which was the most common undersurface color in the later years of WWII.
