Cruisergeo, it's yellow, did not show up in the picture very well. I used a DecoColor Opaque Paint Marker (Broad Line). they are really simple to use. You can get them at arts and crafts stores like 'Michaels'. They come in different size tips, Broad, Medium, Fine, etc.
Some people spray clear over it but I did not want to do that.
Here's one of may places online where you can get them.
