How Do U Revert Colours (theme) Back To Default ?

This might seem like a noob question …
How do u revert the default colours back into Renoise ?
I have messed them up !!!
yes, i have tried reinstalling, colours still bad, i cant see an option to return to default ?? :S

Please help!
maybe some settings saved elsewhere on pc ?

navigate to the renoise app in the bowser (inside renoise).
look at its contents.
go to the resources.
look in the themes folder.
select the default.xml.

it’s true that messing around with the default , can really end up a mess pretty quick !!!
