What is subliminal message?

Coincidence, subliminal message, subconscious symbolism, or what?

• I've noticed some recurrent patterns in music videos (use of numbers, colors, etc.) that have piqued my interest. I'm wondering if any industry insiders can shed any light or if anyone has explored this concept academically or otherwise. Googling has only revealed a bunch of sites about wacky conspiracy mind-control theories. I'm not asking about whether the Illuminati controls Kanye; I'm talking more about videos as a developing art form which includes a unique system of symbology--or perhaps is sprinkled with insider references amongst video professionals, like that industry's version of 1337. For example, the colors red and blue often form the basic palette of a music video. Color symbolism varies, but in Western culture, gender comes to mind: blue being a "male" color and red (more likely pink) a "female" color. However, in the past decade or so, the "red pill vs. blue pill" meme has cropped up in pop culture. Both symbologies refer to a deeper dualism. What I'm wondering is, how much of this is consciously present in the creation of a video and if so, what exactly does it signify (if anything)? I've noticed the number 304 cropping up repeatedly too. In urban slang this refers to "hoe" (as in 304 turned upside down on a calculator). Then there's the HTTP status code 304 which a server will respond with if the website has not been modified since the date and time specified in the request. What I'm wondering about is whether there's any conscious use of this number in a symbolic way (whether related to hoe or HTTP or not) or theories that could explain it. Oftentimes, this number occurs in videos as a time on a clock, as in http://www.youtube.com/watch?v=KV43rJ0a5iA at 3:56 and http://www.youtube.com/watch?v=9xVPrTYRfUk (NSFW) at 2:14. Interestingly, both of these videos allude to Lesbian themes and I wonder if there is any significance to that. The trope also appears in http://www.youtube.com/watch?v=C-u5WLJ9Yk4 video at 0:14; in http://www.youtube.com/watch?v=5R-9IgWD36A at 0:31 and throughout (note color themes as well); and of course in the name of http://en.wikipedia.org/wiki/0304. I'm not sure how 304 might be interpreted in these contexts but it does jump out. There are quite a few other examples of motifs that seem to be emerging in videos; these are just a couple that really stand out to me and I'm wondering if there's anything intentional to the pattern.

  Not sure about the colors, though it seems http://theabyssgazes.blogspot.com/2010/03/teal-and-orange-hollywood-please-stop.html. With respect to the numbers, could you be experiencing http://www.psychologytoday.com/blog/reality-check/201111/11-11-11-apophenia-and-the-meaning-life? A while back, there was a particular 4-digit number that I was notcing all over the place. It even became something of an inside joke between my wife and I. I doubt there was anything more to it than a sudden awareness of it, followed by a healthy bit of confirmation/selection bias. On the other hand, it did provide me with an easy-to-remember PIN (that has no relationship with any of the defaults like birthdays and whatnot), so there's that.
