### 7.10.7 Harmony

From time to time there may be the need to find colors contrasting to or being in harmony with a given start color.

This task is solved with the Harmony dialog. Here is a short description of its concept:

The primary colors are positioned on the edge of a circle. The "light colors" red, green and blue have the same angular distance to each other, so they optically form a triangle. At the opposing positions are their complementary colors, the "print colors" cyan, magenta and yellow. The center of the circle has no saturation: it is black, gray or white, depending on the current lightness. The space between these basic colors is blended continuously.

The color harmony is based on the theory, that equal angular distances between colors and equal distances from the center of the color circle correspond to "nice" color combinations.

PhotoLine offers several methods for creating color combinations. The whole creation is based on the HSV color model. If you are modifying the position of a color marker in the color circle, you can (depending on the chosen method) change the color angle (hue) and the saturation for this or for all colors. By holding Ctrl (Windows) or Command (macOS) only the hue is changed, by holding Shift only the saturation. The slider at the bottom controls the lightness (value).

The created colors can be added to the active color list by using to color list.
