Naw, Photoshop would've taken like a whole minute. This was whole entire seconds of work finding an existing pixel online somewhere:-P.

If you really want to get fancy, you could compute the average coloration across all pixels from the entire image - but would it be recursively applied, i.e. a progressive pixelation process, or all at once in an efficient (both in terms of computation & memory requirements, plus infinitely parallelizable too!) lossless sliding window algorithm?

Or pick the most common (mode rather than average) pixel color, which looks to be the blueish background? What I went for (uh yeah... on purpose, sure...), rather than average, median, or mode, was the longest continuous stretch of coloration, as in longest length vector from one side to the other. The blue tends to be interrupted by other colors while the brown... uh, holds the highest amount of cocaine?

Art can evoke many feelings within the mind of the viewer.

Primarily what I receive from this one is a sense of... "brown":-P.

Ah update. I was confused for a bit because I could read it just fine and couldn't understand why so many people were trying to read the non-HD image.
