green
Contrasting and complimentary colours are the same thing. Green is a secondary colour. You achieved a secondary colour by mixing two of the three primary colour. In this case green is the mixture of Yellow and Blue. The complimentary colour to a secondary colour is the primary colour not used to create it; in this case the complimentary (or contrasting) colour to green is red.
The contrasting color of red is green. These colors are opposite each other on the color wheel, creating a strong visual contrast when used together.
Colour consistency is the variation of the dominant or contrasting wavelength in identical lamp samples. It is also what allows a human to see the same colour in a variety of situations.Colour constancy is the brains ability to assign a constant colour to a surface. For example Granny Smith apples will have a constant green colour.
Red and green are contrasting colours, and green next to red stands out.

They are the opposites on a colour wheel.
It really depends on personal preference. If you pair orange with a colour which is near to it on the colour wheel, then it should look nice to most people, meaning it is a complimenting colour. However, if you put orange with a contrasting colour such as green or blue or purple, then to most people it will look horrible.
