Coin Pattern Orange

How to scratch annoying patterns off of the side of your bmx bike?
I quite like my bike its lite, easy to ride, good condition however the patterns on the side really annoy me. The bike is black with these annoying orange patterns on. The patterns look like they have just been painted on over the top off the black bike frame i tried scratching it off with a coin but as i suspected that didn't work. Does anyone have any idea how to remove the patterns without scratching off the black paint underneath presuming there is black paint underneath.
Where I used to work one of the employees painted lettering on the trucks and removed it. To remove it he used oven cleaner!
If it is stickers that the bike manufacturer did not apply, then auto parts stores have a chemical to help you. If the manufacturer put paint or decal designs and then sprayed clear coat over that then you will need to paint over or sticker over.
