Tea Cups

 Aunt Jane has sixteen cups and saucers, four of each of four colours.

Can you arrange them in a 4x4 grid so that each colour of cup and saucer appears once in each row and column, with each cup/saucer pair occurring once?

Remember that these 16 cup/saucers are all different so, for example, you CANNOT have a red cup on a green saucer somewhere and another red cup on a green saucer somewhere else.
