They'll still have a giant wheelchair emblem painted in yellow on top of the blue background.
Wellington City Council's Social Portfolio Leader, Councillor Stephanie Cook, says it is hoped the initiative will make it more obvious to other motorists that they can't park there.
"I would imagine there's nothing worse for people looking for a park to find someone has illegally parked in the spot they need for greater accessibility. Painting them blue will help make the parks more visible. And it makes it easier for enforcement officers to spot them as well.
"We're basically trialling this at the moment to see if it works better for people with accessibility needs. We want your feedback. Is it working and are the parks easier to spot?" says Cr Cook.
Some mobility parks in Island Bay and Newtown have already been painted bright blue. The Council received some phone calls from people to clarify that they are indeed mobility parks.
"We want people to know that there's no change to the mobility parks - we just want to highlight what they are for ease of understanding," says Cr Cook.
There are some 120 mobility car parks across Wellington city. Should this trial go well, the rest of the parks will be painted blue.

People can also pick up a copy of an accessibility map - which shows where all the parks are - from the Council Service Centre on Wakefield Street, the i-Site visitor centre on Wakefield Street or from Wellington city libraries.
