Jalo painted the steel parts of their hoes. Aluminium wheels, (early models), and aluminium tool frames, (all but very early models), were not painted.
The red on the wheels is, typically, Post Office Red or similar.
Most handles were Green, Mid Brunswick appears to be a worthy match, although I have seen both yellow and light blue which both appeared to be original.
Tools were black. I use Wilko Multi-Surface Enamel Spray in Satin Black which gives a nice “metal black” finish without being over glossy.
Good luck with yours–Steve
