Probably a stupid idea, but I wouldn't mind customizing my helmet a bit.
For a motorcycle but the painting is the same so break out your rattle can, and your masking tape and go to town.Like any other painting task, surface preparation is the most important step in achieving a good final finish.
First thing is to determine what the shell of the helmet is made of... Fiberglass, ABS plastic, etc. Choose a paint formula that's made to be used on that kind of surface.
Next, remove as much of the liner and edge trim as you can, to make it easier to apply the paint without overspray problems.
Once you've decided on your paint and design, get some fine sand paper (220 to 400 grit) and sand the helmet until the surface is as smooth as you can make it. A coat of primer would come next, to give the final paint something to hold on to. Sand that smooth also.
Then use a good quality masking tape to lay out your design and start spraying! Don't forget several coats of clear over the top of your final design, and whatever you do... Once it's finished, DON'T DROP IT!!!
