Hey. I just skipped through the topic pages, so maybe someone has already suggested this, but i have a theory on how they could be doing this.
You mentioned that when looking at a mobile phone screen your eyes can split the Red, Green and Blue colors.
Now i'm not an expert at this, but i believe that all screens, whether it be a TV, PC, phone, etc nowadays work by combining these 3 base colors to
form the final image. (as in shining red, green and blue lights independently) So as you mentioned you see Red letters, maybe what they are doing is
flashing the subliminal messages only in the Red color channel/range for example?
I'm not in USA, so i don't have CBS, FOX or whatever but someone who is, could try searching for these subliminals by using a red color filter.
Good luck trying to figure this out, i'll keep my eye on this topic (:
