Definition - What does Presentation Layer mean? The presentation layer is layer 6 of the 7-layer Open Systems Interconnection (OSI) model. It is used to present data to the application layer (layer 7) in an accurate, well-defined and standardized format. The presentation layer is sometimes called the syntax layer.
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.
What we call white light is light with all possible colors in it.    The color you see when you look at the object is the color of the  light that   remains, AFT â¦ ER the object has absorbed the colors it absorbs.    If it absorbs nothing, then it appears white. If it absorbs  everything except red,   then it appears red.
