“Why is my red signs fading” it’s true red does fade much faster than anything else no matter the material, but not to worry, there is a work around and it’s quite effective.
The science behind it is rather interesting but I will not bore you with the details, I’ll let an expert do that! "The red dyes are more susceptible to fading because they look red and thus absorb blue, and blue is the higher-energy light," notes David Erhardt of the Smithsonian Center for Materials Research and Education.
Well there you have it, all your burning questions have been answered; I have seen a lot of faded red signs that are faded and I’m sure you have too.
The work around is an easy fix for your ‘sign guy’ should be able to help you when you’re the sign is built, the process can be different depending on the materials used and simply put it’s a UV coating to protect the colour pigment.
If you have a red sign please make sure you get it UV coated and remember ”A business with no sign is a sign of no business”
