Well, I’m certainly no expert, but I would think that the size and color of the text wouldn’t matter because the subconscious doesn’t necessarily work like your eyes do. I mean, just look at advertisements: their messages are all sizes and colors and their subliminal messages work in manipulating our minds to buy things. I think the question “Does size and color of text matter?” pairs well with my own question, “If I take my glasses off will my subconscious still get the message?” I would argue “Yes, because my subconscious doesn’t need glasses, my eyes do.” Subliminal messages flash at us so quickly we can’t stop our minds from being affected, the messages aren’t as decipherable consciously, so it doesn’t matter what we see with our eyes in the conscious state, We walk around all day getting bombarded with thousands of subliminal advertisements. We can’t look away fast enough to keep from being subconsciously manipulated.
Companies spend millions on social researchers to conduct studies to find out what kind of messages and images will convince us to spend our money. Researchers have found that the two images that work the best are images of sex and death. There is no end in sight to the use of subliminal advertisements, this is because subconscious advertisement is extremely effective. I know it appears that I went off on a tangent there, but my point is, it doesn’t matter what the sizes and colors of the SB messages are, our subconscious minds can’t help but to “see” whatever messages are thrust at them, no matter how they are presented.
