Answer:
In HTML, the hexadecimal code for the color blue is #0000FF. In hexadecimal numbers (or base 16 numbers), F is the equivalent of 15. So, 0000FF is 255 in decimal form. The square root of 255 is approximately 15.968719423.
So, I believe it is safe to say that the square root of blue is approximately equal to 15.97.

I know some people say the square root of blue is red because the square root of 0.45 nm is .67 nm which is red on the spectrum, but it’s really 0.67 times the square root of a nanometer. What is the square root of a nanometer? I dunno, something to do with fractals… like a measure of distance on a curve with 1/2 a dimension. But then you can’t convert it back to color again. And fractal curves generally have more than on dimension…

For the record, a nanometer is a billionth (1 x 10^-9), not a millionth of a meter , so if you take an arbitrary value of 450 nanometers from the blue range of the spectrum, the square root is about 671,000 nanometers, or a touch over two-thirds of a millimeter wavelength, so is well into radio frequencies. I think this approach to a square root of blue–if there is a valid one–is more logical than the hexadecimal approach, since it takes an actual numerical value for blue as a starting point. I’m not really averse to green as an answer, if there is some rational support for it, but Tmarkl offers none except his standing as a former (?) mathematician. (It’s googol, btw)

After thinking about this question I have come to an considerable answer…The square root of blue is “sadness.” Psychologists say this happens a lot during the Christmas season. Gray days, missing loved ones, rain, snow, the lack of sunshine…all contributes to the root of the square root. And the answer is the square root of red.

Let’s have some fun here and point out that the visible spectrum from violet to red (rainbow) is about 0.45 microns to 0.8 microns. So blue is about 0.45 microns, the square root of 0.45 is 0.67. Thus, a bright red. And the square root of blue is red. Now you would say, but Weatherbyrd what about the zeros. I know a micron is 10^-6 meters. Like I said lets have some fun and do it this way.

The wavelength of blue light is between 450 and 495 nanometers. Therefore, the square root of blue is between 21.2132 and 22.2486 nm, or in other words, the approximate width of a bacteria flagellum.

I was a mathemetician. I knew hex, understood binary, even got a grasping of BIG numbers. Once while travelling on Corfun, I met an amazing mathematician how explained google. This was before computers, so don’t think of search engines. A google was a 1 with 100 zeroes after it. And a really BIG number was a googolplex, which is a 1 with a google of zeroes behind it. But enough of boring stuff.
The square root of blue is green. That is ironic, if you understand colours, but there you go. Life is full of ironies!
