Two Keys
The Two Keys effect allows you to transform an image (change color tints, replace colors, adjust contrast and brightness etc.) using two key colors.

The effect has the following controls that are represented by two color boxes:
Original Key Colors
In the Black Point color plate choose a color that will be used as a black key. In the White Point color plate choose a color that will be used as a white key. By default the corresponding colors are chosen, and your image is in its original state.
How to define the other key colors:
- Click the color plate (the pointer will transform into an eyedropper), choose the necessary color on the image and left-click it. The color box will change its color to the selected one.
- Double-click the color plate to open the Select Color dialog.
New Key Colors
- Note: The color of the black point cannot be lighter than the color of the white point and vice versa.
As a result, all colors that are darker than the black key will shift to the black color; all colors that are lighter than the white key will shift to the white color.
You can also set only one key color (black key or white key). If you define only the black key, the dark colors will shift to the black color, while the light colors will not change.
Please note, that the lighter the black key color is, the darker the image will be; the darker the white key color is, the lighter your image will be.
Note: If you don't want to change the color shades on your image, use the color grey as the key color (in this case the color components (green, red and blue) are equal).
