Melbourne's yellow taxis could be a thing of the past, with one of the city's biggest taxi operators deciding to ditch the iconic colour in favour of black, white or silver.

Operator 13CABS will immediately begin a nationwide rollout of new black, white or silver cabs with orange branding and signage to compete with Uber.

The new-look cars will be bought and incorporated into the fleet.
