Farbtonkurve

Farbtonkurve, meaning "hue curve" in German, is a concept often encountered in digital image editing and color theory. It refers to a graphical representation that illustrates the relationship between original hues and their modified counterparts within an image. Essentially, it's a way to visualize and manipulate how different colors are shifted or preserved.

A typical Farbtonkurve plots the original hue on the horizontal axis and the target or adjusted hue on the vertical axis. By default, this curve often appears as a diagonal line, indicating that each original hue is mapped to itself, meaning no hue shift is occurring.

Users can interact with this curve to selectively alter specific colors or ranges of colors. For instance, if a user wants to make all blues appear more teal, they would adjust the curve in the blue region. Moving a point on the curve upwards in the blue section would shift that blue towards a greener hue, while moving it downwards would shift it towards a more violet hue.

The Farbtonkurve is a powerful tool for subtle color correction, creative color grading, and achieving specific aesthetic effects. It allows for precise control over hue adjustments without necessarily affecting saturation or lightness, offering a dedicated way to manage the color palette of an image. It is often found within color adjustment panels in photo editing software.
