Presets

  “Presets” are a common feature for several Colors commands. You can find its description in Sección 8.1.1, “Características comunes de los colores”.

Color Model

  The Color Model used for the transformation. Choices are RGB (default) and HSL (Hue, Saturation and Lightness).

  The chosen Color Model changes the next settings.

Red frequency, Green frequency, Blue frequency, Hue frequency, Saturation frequency, Lightness frequency

  These sliders determine the frequency multiplier for each component in the color transformation.

Red shift, Green shift, Blue shift, Hue shift, Saturation shift, Lightness shift

  These sliders and angle selectors determine how much of a phase shift from one component to another will be done for the chosen input component.

Keep Red component, Keep Green component, Keep Blue component, Keep Hue component, Keep Saturation component, Keep Lightness component

  These checkboxes allow you disable one or more of the components from being changed. Any component checked here will not be changed by the filter.

Blending Options, Preview and Split view

  These are common features described in Sección 8.1.1, “Características comunes de los colores”.
