Why do you call that flower a "red" rose ? Could it be because it appears red in
typical 'wideband' solar or household light ? That must mean that when light of
many colors shines on it, the rose absorbs everything except red, and red is
the only light left to bounce off of it toward your eyes. If that's the case, and you
illuminate it with light of any single color other than red, then the rose will absorb
that light and appear black.

Blue.
Assuming that the light you are shining on the object is white, then the object is also blue. Objects appear a certain color because they reflect that color to our eyes and the rest of the colors in the light are absorbed by the object.
The object will appear to be blue. However, the object would be indistinguishable from an object that reflects all colors of light. If yellow light were shone on an object that reflects only blue wavelengths, the object would appear to be black.

Everything obsorbs or bounces light off of itself. There are also many wavelengths and different types of light around us. This blue object obsorbs each and every color except the blue you are seeing. The blue light reflects off of the object, thus making it appear blue to your eyes.
Black
Blue is blue because things that are blue actually repel the frequency of light from the sun that would appear blue. Because that is the only color light that is reflected, that is the only color that we see. Things that are blue are actually every color BUT blue!
blue
they do not, the sky is a blue color because that is the color of light that breaks through the atmosphere. if air molecules did make the sky appear blue, then how would you explain a sunset?
yellow-green
turquoise(or turquiose)
Assuming that the light you are shining on the object is white, then the object is also blue. Objects appear a certain color because they reflect that color to our eyes and the rest of the colors in the light are absorbed by the object.
