1) Another major factor that affects color in TZ are color filters. There are 30 basic color filters listed under the Color-1 and Color-2 menus. If you are using the Iterations filter there are an additional 20 filters there. As you can see in this image the filter is selected as "None" but change that to Filter 6.
2)
We will now work with the basic color controls. There are three ways to access this. One way to access this is from the Color menu and then selecting Color Parameters. Another way is to click on the C on the side toolbar (Out of view in this screenshot). The third way and the one I use is shown in the next image below.
3)
The easiest way to quickly access the color controls is simply to click your RIGHT mouse button over the image. This will pop up a small menu where you can select Color Controls.
4)
You should now see the new color control window. There are three primary colors Red, Green & Blue. In this window you can see that the Red has a value of 3, Green a value of 5 and Blue a value of 5. These can all be changed for a variety of combinations.
Below these boxes you will see five control buttons, Forward, Reverse, Inverse, Cycle and Apply. By selecting Forward or Reverse you can cycle the color combination selected incrementally, a click at a time. The Inverse will reverse the color selection ( I rarely use this function ). The Cycle button is used to rapidly cycle the colors in the image to quickly see changes to the image. The Apply button is used to apply any changes you have made in the Red, Green or Blue to the image.
Let's move on to the next steps.
