Since people are warning you over light colors, thought I would provide a real life example. This is yellow printed on cheap Amazon clear decal sheets next to some professional decals. I will look into high quality paper in the future, as the cheaper decal sheets are too thick compared to professional decals.
Needless to say, I removed it and used professional decal number and letters. The yellow custom logo is printed on white decal paper. It shows upuch better.
Have fun.
