Definition - What does Presentation Layer mean? The presentation layer is layer 6 of the 7-layer Open Systems Interconnection (OSI) model.

As shown in the next figure, an object is seen as black if it absorbs all colors of white light. A white object reflects all colors of white light equally. If an object absorbs all colors but one, we see the color it does not absorb. The yellow strip in the following figure absorbs red, orange, green, blue, indigo and violet light. It reflects yellow light and we see it as yellow. The eye also uses complementary colors in color vision.
To answer your question more generally, all colors absorb and reflect heat, however, different colors do it better or worse than others. Typically, lighter colors reflect more heat and darker colors absorb more heat. If you've even worn a black shirt on a hot day, you'll notice this.o, yes: blue does absorb heat. However, as you know, there are many shades of blue. Darker blues will absorb more heat (royal blue for example) and lighter blues will absorb less heat (baby blue). A general rule of thumb is: the darker the color, the more heat that color will absorb.
