When you check again for temperature you should fine that they are all the same. If you are so inclined, then take those same samples and place them in total darkness. This is because the black sample absorbs all of the suns energy and does not reflect any. You should notice that the black sample is the hottest and the white the coldest. After exposure to the sun for a while, feel the different samples. Be sure that all the samples are made of the same stuff and be sure to include white and black. Try this, take samples of the same materials in different colors and lay them out in the sun. And by scale, all the other colors are different measures of the same light except that which is accepted and that not accepted is reflected to present the color we see (example: electromagnetic radiation at 700nm = red). White reflects everything, black reflects nothing. All colors are perceived by humans as the quality of light that is absorbed vs what is reflected. Black(ness) (not previously defined) is the absorption of all light. Dark(ness), as stated is the absence of light. Black(ness) is the exact opposite of darkness, without regard to the obvious optics. I did not notice a mention of the truest quality of black or blackness, and some miss statements of what blackness is.
