If you are talking about light, blue can be shown by passing light through a prism. An object is blue because the object absorbs all the colors of light, but reflects blue back so that we can see it. In art blue is made from certain chemical combinations. It is also made from crushed synthetic and natural ultramarine. Since blue is a primary color, it can't be made from combining any other color.
