The Delhi Metro Rail Corporation (DMRC) today announced that the colour code of the upcoming Delhi Aerocity to Tughlakabad Metro corridor will change from 'silver' to 'gold'. The DMRC said in a release that the gold colour is visible more prominently and clearly on the trains over silver. It added that silver tends to mix with the overall texture of the stainless steel body which has a similar colour. The DMRC hopes that the change in colour will bring greater visibility and convenience for the passengers.<br />''<br />''The Aerocity – Tughlakabad Metro corridor of Delhi Metro's Phase IV will be over 23 kilometres long with 15 stations.
