Master trainer Bart Cummings' famous green and gold silks will be protected as recognition of his contribution to racing over the past 60 years.

The Australian Racing Board said on Tuesday the colours could not be used for another 50 years even if they were retired before then.

"Under the rules of registration, no-one can replicate the silks before 31 July, 2063, even if they are retired at some stage in the future," ARB chief executive Peter McGauran said.

"Bart Cummings is an iconic figure in Australian racing who has been at the forefront of his profession across seven decades.

"His accomplishments are staggering.

"His achievements and records can never be broken. He is a unique figure in history. As Bart commences a training partnership with his grandson James Cummings, racing wants to honour him in a way especially important to him - preservation of his racing colours."

The green and gold silks have been worn by many of Cummings' 266 Group One winners including dual Melbourne Cup winner Think Big (1974-75) and 1991 Caulfield-Melbourne Cups winner Let's Elope.

Cummings celebrated his 60th anniversary as a trainer earlier this year. During that time he has racked up an incredible 266 Group One wins including the 12 Melbourne Cups which have made him a household name.

The 85-year-old entered into a partnership with his grandson from August 1 with the pair striking almost instant success with a double at Randwick on Saturday including stakes success with Eurozone, winner of the Listed Rosebud.

Eurozone sports another set of familiar colours for the Cummings stable, the black and white chess board squares of long time client Dato Tan Chin Nam, the owner of Think Big and fellow Cup winners Saintly and Viewed.
