A DeviceLink contains one set of curves for each primary color at the input of its lookup table, and another set of curves at the output. These Input Tonality and Output Tonality curves are distinct from other types of curves in ColorFlow, such as device, simulation, or conversion curves. Input Tonality and Output Tonality curves exist in a DeviceLink for both curve-controlled devices and non-curve-controlled devices. You can view and adjust the Input Tonality and Output Tonality curves of a DeviceLink.
