 The _color balance RGB_ module expects a scene-referred linear input and produces a scene-referred RGB output, which may or may not be linear, depending on the module settings (_contrast_ and _power_ will delinearize the output).
 
-At its output, _color balance RGB_ checks that the graded colors fit inside the pipeline RGB color space (Rec 2020 by default) and applies a soft saturation clipping at constant hue, aiming to retarget out-of-gamut color to the nearest in-gamut color by scaling both chroma and lightness. This prevents the chroma and saturation settings from pushing colors outside of the valid range and allows more drastic adjustments to be safely used.

-: This parameter is the power function applied to the output transfer function, and it is often improperly called the _gamma_ (which can mean too many things in imaging applications, so we should stop using that term). It is used to raise or compress the mid-tones to account for display non-linearities or to avoid quantization artifacts when encoding in 8 bit file formats. This is a common operation when applying ICC color profiles (except for linear RGB spaces, like REC 709 or REC 2020, which have a linear “gamma” of 1.0). However, at the output of _filmic rgb_, the signal is logarithmically encoded, which is not something ICC color profiles know to handle. As a consequence, if we let them apply a gamma of 1/2.2 on top, it will result in a double-up, which would cause the middle-gray to be remapped to 76% instead of 45% as it should in display-referred space.

 latitude
 : The latitude is the range between the two nodes enclosing the central linear portion of the curve, expressed as a percentage of the dynamic range defined in the [_scene_](#scene) tab (white relative exposure minus black relative exposure). It is the luminance range that is remapped in priority, and it is remapped to the luminance interval defined by the contrast parameter. It is usually advisable to keep the latitude as large as possible, while avoiding clipping. If clipping is observed, you can compensate by either decreasing the latitude, shifting the latitude interval with the _shadow ↔ highlights balance_ parameter, or decreasing the contrast.

 : The target black luminance parameter sets the ground-level black of the target medium. By default it is set to the minimum non-zero value that can be encoded by the available number of bits in the output color space. Reducing it to zero means that some non-zero luminances will be mapped to 0 in the output, potentially losing some detail in the very darkest parts of the shadows. Increasing this slider will produce raised, faded blacks that can provide something of a "retro" look.

 Since all of these strategies were approximations (and often over-conservative ones) _v6 (2022)_ introduces a more accurate and measured approach. It performs a test-conversion to display color space, checks if the resulting color fits within the [0; 100]% range, and if it doesn't, computes the maximum saturation available in gamut at this luminance and hue, finally clipping the color to this value. This ensures a minimal color distortion, allowing for more saturated colors and better use of the available gamut, but also enforces a constant hue throughout the whole tone mapping **and** gamut mapping operation.
 
-This gamut mapping uses the output color profile as a definition of the display color space and automatically adjusts to any output space. However, only _matrix_ or _matrix + curve(s)_ ICC profiles are supported. _LUT_ ICC profiles are not supported and, if used, will make the gamut mapping default to the pipeline working space (Rec 2020 by default).

 Note that the hue used as a reference for the gamut mapping is the hue before any tone mapping, sampled at the input of filmic. This means that even the _none_ chrominance preservation mode (applied on individual RGB channels regardless of their ratios) preserves hue in _v6_. This mode will only desaturate highlights more than the other modes, and a mechanism is in place to prevent it from resaturating shadows -- this behaviour can be bypassed by increasing the _extreme luminance saturation_ setting.

 : Activate a color clipping mechanism. In most cases you can leave this control in its default “off” state.
