1. Method of producing olive colour dye for dyeing protein, polyamide fibres and leather, in a form of a powder containing asymmetric chromium complex type 1:2 dye with the general formula 1, where M signifies atom of hydrogen, alkaline metal or alkaline earth metal, or ammonium group, dust preventing agents based on mineral oils and possibly filler agents, involving interfacing 6-nitro-1, 2-diazoxynaphthalenesulfonic-4 acids with naphthol in alkaline aqueous environment; converting obtained monoazo compound dye with formula 2, into chromium complex type 1:1 by applying trivalent chromium salt in acidic aqueous environment at more than 100 degrees C under pressure, subjecting the obtained chromium complex type 1:1 monoazo compound dye with formula 2 to reaction with yellow monoazo compound dye with formula 3, created by mixing diazoxide 4-nitro-2-aminophenol in alkaline aqueous environment with acetylene acetic in aqueous environment in increased temperature, preferably exceeding 50 degrees C, involving reaction of chromium complex type 1:1 dye with the general formula 2 with yellow dye with formulae 3 conducted with pH more than 4, preferably with pH=5-7, subsequently aliphatic alcohol sodium sulphite, preferably lauryl alcohol and/or sodium salt succinate, are applied to the received compound mixture, containing asymmetric chromium complex type 1:2 dye with formula 1...<IMAGE>
