That depends on a few things:
1. The color. Some colors are more prone to fading.
2. Whether you case the guitar when not in use, or hang it or put it on a stand in natural or artificial light; and also, how much light and for how long?
Lots of variables here.
In any event, without going into a long song and dance, the dyes used are organic and are sometimes light sensitive. If you keep the guitar cased when not in use, you won't see noticeable fading, or if you do it will be slight and take a very long time. If you hang it, or keep it out on a stand, you might see some fading depending on the color, how strong the light is, and how long it's exposed to light.
Some inorganic stains are less prone to fading than organic stains, but they don't show the wood grain very well, so most guitar makers don't use them.
Bottom line, if you're concerned about fading, keep the guitar cased when not in use. If you're less concerned about that, do your thing!
I keep mine cased, but for other reasons, like buffering temperature and humidity changes that take place during the day, and keeping dust out of the control pots, etc.
Thank you for the detailed response boss!
Another relevant question. Is the colour blue more prone to fading? I remember a couple of users mentioning it on this forum but I don't know how true it is.
There is entropy in the universe. About the most you can do is sit down.

Bought this guitar back in 2012. Never cared for the Custom 24 but I loved this color so much. Took a few pictures the day it arrived. Since then I rarely played it but was crazy about it´s looks. The following years I kind of lost my feelings for it more and more. I´d sometimes stumbled across this picture since it was on my Facebook but it kind of felt that I did not own this guitar anymore, even thou I did.
On a sunny day during Wimbledon 2015 I thought it was a good time to bring out all my guitars and take some photos in good light.
I was shooting from all possible angles and in different lights but it just looked dull and boring to me. When I saw the old picture I was trying to work out why they differed so much. Was it the light in the old apartment, was it my new phones camera. Did the flash create the vivid colors back then? I knew in the back of my head from the days on BAM where people tried to age their guitars, and people said that the finish PRS used did not fade like old Gibsons and Fenders did. So that never crossed my mind, and the guitar was kept in a rack most of the time away from the sun anyways.
This week I decided to sell it and took it apart and cleaned it up. I did not care for it as much as I should. As I removed the bride pick-up I discovered what had happen.
So I was not going crazy. The finish had changed. I googled and found out that blue is among a few colors that indeed will fade. Shame since I love blue guitars. Have had others but never for more than a year or so before selling them again, so I had never experienced the fading. Had my eyes on my dream guitar: A matteo blue 20th artist singlecut trem, but I´ll have to go for the next best thing now. Green guitars, and maybe a nice green fade or eriza verde and hope they will keep their looks.
The blues fade almost as nice as the emerald green ones do...... The finish had changed. I googled and found out that blue is among a few colors that indeed will fade.
