Yes, yes I do.....and my dark side is apparently Blue :)

Use the "Fn" key and the key that looks like a sun.  One is up and the other is down.

to make it visible in the dark sky at night( white is the most contrasting colour to black syk)

Blue! (I checked!)lol

Man u need a reality check.  Are u writing a thought in English or are you a space cade?

no, it does not. in physics, balck is not a colour. in the visible part of the electromagnetic spectrum, there is no black. a total absence of any colour is represented by black in physics. black holes are so named because they have such a strong gravitational force that they even attract light and do not allow it to escape. hence the name

It is all throughout space if it exists.  You can't see it because...well...it is dark ;0)

You mean, what color is the sky on the moon?  No color, or black.  The moon doesn't have an atmosphere.

reflection of light\n\nDuring daylight the sky has the appearance of a deep blue surface, but this is the result of the air scattering sunlight. [1] There is no "blue object" above the earth in any normal sense, so it is hard to say what object the sky is. The sky is thus sometimes defined as the denser gaseous zone of a planet's atmosphere. At night the sky has the appearance of a black surface or region scattered with stars. But if we then say that the sky is the entire visible universe, it would not be the same thing we see during the day.

Possibly because you are colorblind and can not see the color blue.\n\nOr because you are blind and can not see.\n\nOr, how about because it is night time, and the increase of light from our sun isn't exciting particles of water to make the spectrum blue.  Instead, the absence of such light allows us to not see this type of distortion and see into space properly. \n\nOr, because the density of the clouds has reached a critical point and it is about to storm or rain.\n\nOr because you are weating sunglasses that distort your view.\n\nLOL this is a very subjective question witout the proper context.

Here is something interesting to think about: When you look at the sky at night, it is black, with the stars and the moon forming points of light on that black background. So why is it that, during the day, the sky does not remain black with the sun acting as another point of light? Why does the daytime sky turn a bright blue and the stars disappear? \n\nThe first thing to recognize is that the sun is an extremely bright source of light -- much brighter than the moon. The second thing to recognize is that the atoms of nitrogen and oxygen in the atmosphere have an effect on the sunlight that passes through them. \n\nThere is a physical phenomenon called Rayleigh scattering that causes light to scatter when it passes through particles that have a diameter one-tenth that of the wavelength (color) of the light. Sunlight is made up of all different colors of light, but because of the elements in the atmosphere the color blue is scattered much more efficiently than the other colors. \n\nSo when you look at the sky on a clear day, you can see the sun as a bright disk. The blueness you see everywhere else is all of the atoms in the atmosphere scattering blue light toward you. (Because red light, yellow light, green light and the other colors aren't scattered nearly as well, you see the sky as blue.)
