I realise this has been discussed plenty in the past. Some seem to believe strongly it was either a brown shade, others a greenish hue. However, someone I talked to said he had spoken to a few guys at the Army Museum and seen the uniforms in the collection, and concluded without a doubt that the uniforms had a brownish shade to them. And that only the officer tunics could have a very slight greenish tint to them.
Thoughts (beyond 'its your toys')?
