A profile elastomer material for a windscreen wiper blade has an elongated shape and comprises a tapered edge (2) for wiping a glass surface and a mounting edge (3) for connection to a blade-holder frame. The base material of the profile (1) is a mixture of elastomer materials containing an additive able to modify uniformly the colouring of the base material. The additive is chosen from among materials able to discolour uniformly and make the base material of the profile (1) transparent or from among pigments able to impart to the said profile (1) a colouring which is uniform and stable over time.
