To use the color tool, first create a blank palette using the Add Palette tool and add a single piece to it:
The overall color of the piece should match the color you want to select by. When you add a single piece to a palette, the color tool is activated. This is indicated by the blue and red icon changing from a faded to a bright color.

| Color tool is faded before piece is added to palette. |
 |
| Color tool is bright when a single piece is on the active palette. |
When the user taps the red and blue color tool icon, all pieces having a similar average color are added to the palette. The sensitivity of the color tool is controlled by a setting in the preferences screen. Tap the gears icon to view the preferences screen.
When the Color Sensitivity slider is adjusted, help text is displayed near the bottom of the preferences screen. With the slider set to the minimum value (0.05 is the minimum), only very similar average colors are selected, as illustrated here:
All pieces having the same average color have been added to the palette containing the sample piece. With the slider set to a higher value, more pieces, with more varied colors are added to the palette:
One other setting affects the pieces that are selected. On the Preferences screen there is a setting called "Ignore Hidden Palettes when Selecting". If this is set to ON, then any palettes hidden off-screen will be ignored when selecting pieces. In the examples shown above, there are only two palettes, the original palette containing all scrambled pieces, and the palette being used by the color selection process, so this setting has no effect.
