How many pieces are in a standard LEGO bucket?

LEGO first came to the shops in the 1960's and the standard Lego set contained 25 pieces. There are many Lego sets available on the market but the standard Red Lego bucket contains 480 pieces, whereas the yellow bucket contains 607 pieces and the blue bucket contains 700 pieces. So there is no real standard as the application dictates the size of the Lego bucket.
