Be it red, white or yellow, roses convey so much alone or in a bunch, or matched with other, complementary flowers. If you learn a bit about the âfloriographyâ of the different colors of roses you can understand their true meaning and the color you choose can add special meaning to your gift.
White light contains all the wavelengths of the visible spectrum at  equal intensity. The different colors of light, except violet, are  absorbed when white light shines on â¦ an opaque violet object. The  violet color is reflected.
Black absorbs light. Therefore none (or very little light) is reflected. The result is a black surface. Objects that are blue say, absorb all the other colors, and reflect ONLY the wavelenth(s) corresponding to that shade of blue. Same holds for any other color. White, on the other hand reflects light.
