linear, so the colors spread evenly across the full density range. The color distribution is visible in the
colored palette illustration to the left of the Curve control in the Settings panel.
Figure 11. Over a narrow Signal Density range, the color curve is set to 1.
When the Curve control is set to 0.5, as shown in Figure 12, the best color resolution is in the upper half of
the density range, and only the dark blues are assigned to densities below 50%. Note the difference in
the palette illustration.
Figure 12. Adjusting to values less than 1, increases the contrast for viewing events in the top half of the selected
density range.
In Figure 13, the Curve control is increased to 3. The majority of colors shifts to the lower half of the
density scale, but various shades of orange and red are still available for densities above 50%.
Figure 13. For color curve settings greater than 1, better contrast is provided for events near the low end of the
density range.
