Clear red neon is the easiest to read neon color. You don't need huge lettering to create an easy to read, highly visible neon sign. Two inch tall neon lettering is readable from more than 60 foot away. This is a real photo of our storefront with two and a half inch red neon letters and 15 millimeter Horizon Blue window border outline.
