Number Coloring
Number Coloring is a tool to enhance visual perception of
ticket numbers displayed in various tables.
Example:
- Open lottery Expert Lotto 6/49.
- Click menu Winning Numbers - Show As - Table.
- Click Select button in Winning Numbers Table window and
select All draws.
- Click Date column header to sort the draws in descending
order.
- Highlight the 10 latest draws in the table.
- Press On/Off button in number coloring toolbar to
turn the number coloring on:

The winning numbers table will look like this:

You may note that for example number 4 in draw 2010/26 Wed 2nd has white background. That is because number 4 hasn't been found in the
selected 10 latest draws. On the other hand number 18 in the same draw
has blueish background to indicate that it appears two times in the
selected draws. Number 6 in draw 2010/25 Wed 1st has yellow background
which means it was drawn three times within the latest 10 draws.
This way you can quickly evaluate the frequency of each pool
number in the selected set of draws or tickets because number coloring
generated from winning numbers table is automatically transferred to
other application windows displaying draws, tickets or just separate
ticket numbers. If you find number coloring too distracting you can
turn it off by clicking On/Off button in the toolbar: 
You can also hide number coloring
toolbar using menu View - Toolbars - Number Coloring to turn it off.
Click menu Tools - Options - Number Coloring - Ticket Tables
to customize the default colors. The options window also contains switch Include bonus numbers. When this switch is turned off then the number frequency coloring will be calculated from the main numbers of selected tickets only.
