How do I customize the colors of the puzzles?
Numerical Fill-In Generator Version 2.0 includes the option to change the color scheme for each of the puzzle sizes.

The color schemes are separated by puzzle size. Each puzzle size has four different color values:
Background
This is the color of the puzzle for the selected puzzle size.
Primary
This is the main color of the checkboxes and text for the selected puzzle size.
Secondary
This is the alternate color of the checkboxes for the selected puzzle size. To make
it easier to distinguish the length of the numbers at a glance, set this color to a
different color than the Primary color. If you prefer to have all of the
checkboxes one color similar to the appearance of a printed puzzle, then make this color
the same as the Primary color.
Checked
This is the color of a checkbox that has been checked off of the list of
numbers to be filled in. Use this color to distinguish between numbers filled into
the puzzle grid and those that have yet to be filled into the puzzle grid. If you
wish, you can set this color to the Background color so the number disappears
completely (only for viewing, the checkbox will still be there). This may get
confusing if you make a mistake however, so it is not recommended for novice users.
To change a color, click on the color box that you wish to change. When you do, the Windows Color dialog box will appear.

Select a color and press the OK button to make a change. Press the Cancel button to back out of the procedure. If you want to select a different color than one that is shown, clicking on the dialog's Define Custom Colors >> button will show a larger grid where you can select the specific combination of red, green, and blue tints. You can select that color by selecting a square to place the color (such as the square selected in the example picture) and click on the dialog's Add to Custom Colors button.
The Options menu will allow you to save your current color settings (Save Color Scheme) or reset them to the program's default colors (Restore Default Colors).
If you attempt to exit the Color Preferences screen without saving your changes to the color scheme (if any were made), the program will ask you to confirm your desire to exit without saving.
