Effect operates with three channels: Red, Green and Blue. Each channel is represented as a scale, and a slider, which is a triangle.
You can do the following operations with the triangle:
by moving it to the right/to the left you can reduce/increase the level of presence of the color in the image (the color, which channel you are shifting,
to increase or decrease the size of the rectangle, left-click and the corner of the triangle and move the cursor toward/away from the center of the rectangle. Increasing or decreasing the size of the rectangle, you increase or decrease the intensity of the color in the current channel. The color changes only if it is present in the picture,
to change the color of the triangle, you should press the left button on the white point in the peak of the triangle and drag it to another peak. For example, we have changed the red triangle of the red channel for a dark blue triangle. As a result everything that was dark blue in the original image becomes red.
to change color of the triangle so that it consists of two color sectors. For this purpose you should press the left button on the white point in the peak of the triangle and drag it to the other side of the triangle. For example, if you make a triangle consisting of dark blue and red colors in the green channel, the new green color of the image will consist of old dark blue and red.
to change color so that the triangle consists of three color sectors. For this purpose you should press the left button on the white point in the peak of the triangle and drag it into the triangle. For example, if in the blue channel you will make a triangle consisting of three colors, the new dark blue color will consist of a color mixture.
