The 5k has a reputation of being "the world's happiest race", with people of all abilities taking part.
The runners set off at Titanic slipways dressed in white clothing and every kilometre a different coloured powder was thrown in the air to decorate the competitors.
This is the first year the event has come to Belfast and all money raised will go to Cancer Research UK's Stand Up to Cancer campaign.
The Color Run also kick-started the new year-long partnership between the charity and Ulster Rugby.
Ulster and Ireland player Paddy Wallace said: "It's a great way to get some exercise with all your friends and family, enjoy yourselves and importantly it's also a brilliant way to raise money for a good cause which is why we are delighted to lend our support to Stand Up To Cancer."
There were no winners or official times taken and people of all ages took part.
Jenny Hall, Marketing Controller for presenting sponsor Dulux, said: "We feel passionately about the positive impact colour can have on us and the places in which we live.
"Being able to bring The Color Run to Belfast is another way for us to bring our mission of 'adding colour to people's lives' to life, as the ultimate celebration of just how uplifting colour can be."
Michael Graham, of Titanic Quarter, commented: "This is the latest in a long list of high-profile sporting, entertainment and fun events to take place at Titanic Quarter."
The first Color Run event was organised in the US in 2012.
