The only rule where colours are concerned is... MIX THEM UP

Single colour lines do turn up every now and then and in some years not at all.

Here in The Colour Configurations we'll show you how the 5 Main  Ball Numbers are divided into three different Colour Groups. This is simply based on how often an individual number has repeated since it was first drawn as opposed to how many times it has been drawn. There is a close relationship but it's not the be all and end all.

The Colours are -

Red (Leading Numbers) These numbers have simply repeated more often than Blue or Green numbers.

Green (Following Numbers) These numbers have repeated more often than Blue numbers but not as often as Red numbers. 

Blue (Trailing Numbers) these numbers were among the last to be drawn following the first draw in 2004.

An important thing to remember is that all numbers appear on average between 8 and 13 times a year regardless of which group they belong to so there's no such thing as hot and cold numbers.

It just means that generally, blue numbers were drawn much later than the other two colour groups and they would need to repeat consecutively for several draws in order to move up into another colour group.

This is why it's important, when choosing your numbers, try to select numbers from two or three colour groups rather than just one colour group. There has only been 26 draws to date where all numbers were from just one colour group.

Incidentally, for those of you who play a line of so called Hot Numbers (which theoretically would be all red numbers) only 7 draws since 2004 have ever contained all red numbers, only 19 have contained all Green numbers and no draw has ever seen a line of all Blue numbers.
