Colorv1coreTempered

Overview

The whole colour page in one node, applied in a fixed order — because the order is the craft. Balance, tonal wheels, contrast about a pivot, mixer, saturation and hue, six vector zones, curves, qualifier.

How to

Balance first.
Shape tone, then contrast about the pivot you choose.
Reach for the vector zones only for a hue that needs its own treatment.

Parameters

Parameter	Type	Default	What it does
lift	Color	[0.0, 0.0, 0.0, 0.0]	Raises the blacks without touching white.
gamma	Color	[1.0, 1.0, 1.0, 1.0]	Bends the midtones with a power curve; ends stay put.
gain	Color	[1.0, 1.0, 1.0, 1.0]	Multiplies the signal — the main brightness/strength control.
offset	Color	[0.0, 0.0, 0.0, 0.0]	Adds a constant to every pixel.
temp	Float	0.0	Colour temperature: negative cools (toward blue), positive warms (toward amber), as a white-balance offset on the whole picture. Balanced against `tint`.
tint	Float	0.0	The green–magenta axis of white balance: negative pushes green, positive magenta. Use it after `temp` to take a cast out of skin.
contrast	Float	1.0	Steepens (>1) or flattens (<1) the response around the pivot.
pivot	Float	0.435	Contrast rotates the tone curve ABOUT this value, so the pivot itself never moves. 0.435 holds the midtones while the ends travel; drop it and contrast crushes the blacks instead of opening the highlights.
saturation	Float	1.0	Colour intensity: 0 = grayscale, 1 = unchanged.
hue	Float	0.0	Rotate every hue by this many degrees around the wheel. Small values only — it moves skin as much as skies.
mixer_rr	Float	1.0	Channel mixer: how much of the input RED lands in the output red. 1 is unchanged.
mixer_rg	Float	0.0	Channel mixer: how much of the input GREEN lands in the output red.
mixer_rb	Float	0.0	Channel mixer: how much of the input BLUE lands in the output red.
mixer_gr	Float	0.0	Channel mixer: how much of the input red lands in the output GREEN.
mixer_gg	Float	1.0	Channel mixer: how much of the input green lands in the output green. 1 is unchanged.
mixer_gb	Float	0.0	Channel mixer: how much of the input blue lands in the output green.
mixer_br	Float	0.0	Channel mixer: how much of the input red lands in the output BLUE.
mixer_bg	Float	0.0	Channel mixer: how much of the input green lands in the output blue.
mixer_bb	Float	1.0	Channel mixer: how much of the input blue lands in the output blue. 1 is unchanged.
mixer_preserve	Bool	false	Keep each output channel's mixer weights summing to one, so remixing the channels never changes the overall brightness — only the colour.
mixer_mono	Bool	false	Send the same mix to all three outputs: a black-and-white conversion whose weights you choose (a red-filter look weights red up).
red_den	Float	0.0	Hue vs: density of the reds — negative lightens them, positive darkens them, the other hues untouched.
red_sat	Float	1.0	Hue vs: saturation of the reds alone. 1 is unchanged.
red_hue	Float	0.0	Hue vs: rotate the reds by this many degrees without moving any other hue.
yellow_den	Float	0.0	Hue vs: density of the yellows — negative lightens, positive darkens.
yellow_sat	Float	1.0	Hue vs: saturation of the yellows alone. 1 is unchanged.
yellow_hue	Float	0.0	Hue vs: rotate the yellows by this many degrees.
green_den	Float	0.0	Hue vs: density of the greens — negative lightens, positive darkens (foliage, screens).
green_sat	Float	1.0	Hue vs: saturation of the greens alone. 1 is unchanged.
green_hue	Float	0.0	Hue vs: rotate the greens by this many degrees.
cyan_den	Float	0.0	Hue vs: density of the cyans — negative lightens, positive darkens.
cyan_sat	Float	1.0	Hue vs: saturation of the cyans alone. 1 is unchanged.
cyan_hue	Float	0.0	Hue vs: rotate the cyans by this many degrees.
blue_den	Float	0.0	Hue vs: density of the blues — negative lightens, positive darkens (skies).
blue_sat	Float	1.0	Hue vs: saturation of the blues alone. 1 is unchanged.
blue_hue	Float	0.0	Hue vs: rotate the blues by this many degrees.
magenta_den	Float	0.0	Hue vs: density of the magentas — negative lightens, positive darkens.
magenta_sat	Float	1.0	Hue vs: saturation of the magentas alone. 1 is unchanged.
magenta_hue	Float	0.0	Hue vs: rotate the magentas by this many degrees.
qual_enable	Bool	false	Limit the whole grade to a qualified colour: hue, saturation and luminance windows multiplied together (the BS_HueQualifier engine, one implementation). Off grades everything.
qual_hue_center	Float	180.0	Qualifier: the hue the window is centred on, degrees — 0 red, 120 green, 240 blue.
qual_hue_width	Float	360.0	Qualifier: how many degrees of hue qualify fully. 360 is every hue.
qual_hue_soft	Float	10.0	Qualifier: degrees of soft shoulder past the hue width, each side.
qual_sat_low	Float	0.0	Qualifier: saturation below this does not qualify.
qual_sat_high	Float	1.0	Qualifier: saturation above this does not qualify.
qual_sat_soft	Float	0.1	Qualifier: the soft shoulder on both saturation limits.
qual_lum_low	Float	0.0	Qualifier: luminance below this does not qualify.
qual_lum_high	Float	1.0	Qualifier: luminance above this does not qualify.
qual_lum_soft	Float	0.1	Qualifier: the soft shoulder on both luminance limits.
qual_invert	Bool	false	Qualifier: grade everything the windows do NOT select.
qual_clean_black	Float	0.0	Qualifier: matte values at or below this go to 0 — cleans near-misses out of the unqualified area.
qual_clean_white	Float	0.0	Qualifier: matte values at or above this go to 1 — solidifies the core of the selection (0 = off).
curve_master	Lut	2 points	A custom curve on all three channels, input level to output level. Identity (two points on the diagonal) does nothing.
curve_r	Lut	2 points	A custom curve on the red channel alone.
curve_g	Lut	2 points	A custom curve on the green channel alone.
curve_b	Lut	2 points	A custom curve on the blue channel alone.
view	Choice	result	The display transform for viewing only — it never changes the pixels in the graph. `resultmatte`
hdr_enable	Bool	false	Turns on the six tone-zone wheels. Off by default so an existing grade never changes underneath you.
hdr_width	Float	1.0	How far each HDR zone reaches. Wide behaves like lift/gamma/gain; narrow is surgical and can band on a smooth gradient. The zones always sum to one, so a uniform move across all six equals one global move.
hdr_black_exp	Float	0.0	HDR palette: exposure of the BLACK zone in stops — the deepest tones, spaced perceptually so it moves the blacks without lifting the shadows.
hdr_black_sat	Float	1.0	HDR palette: saturation of the black zone. 1 is unchanged.
hdr_black_col	Color	[0.0, 0.0, 0.0, 0.0]	HDR palette: a colour offset added in the black zone only — tint the blacks.
hdr_dark_exp	Float	0.0	HDR palette: exposure of the DARK zone in stops, just above the blacks.
hdr_dark_sat	Float	1.0	HDR palette: saturation of the dark zone.
hdr_dark_col	Color	[0.0, 0.0, 0.0, 0.0]	HDR palette: a colour offset in the dark zone only.
hdr_shadow_exp	Float	0.0	HDR palette: exposure of the SHADOW zone in stops — open the shadows without touching the blacks.
hdr_shadow_sat	Float	1.0	HDR palette: saturation of the shadow zone.
hdr_shadow_col	Color	[0.0, 0.0, 0.0, 0.0]	HDR palette: a colour offset in the shadow zone only.
hdr_light_exp	Float	0.0	HDR palette: exposure of the LIGHT zone in stops — the upper mids.
hdr_light_sat	Float	1.0	HDR palette: saturation of the light zone.
hdr_light_col	Color	[0.0, 0.0, 0.0, 0.0]	HDR palette: a colour offset in the light zone only.
hdr_high_exp	Float	0.0	HDR palette: exposure of the HIGHLIGHT zone in stops.
hdr_high_sat	Float	1.0	HDR palette: saturation of the highlight zone.
hdr_high_col	Color	[0.0, 0.0, 0.0, 0.0]	HDR palette: a colour offset in the highlights only.
hdr_spec_exp	Float	0.0	HDR palette: exposure of the SPECULAR zone in stops — the very top, so speculars move without the highlights following.
hdr_spec_sat	Float	1.0	HDR palette: saturation of the specular zone.
hdr_spec_col	Color	[0.0, 0.0, 0.0, 0.0]	HDR palette: a colour offset in the speculars only.
warp_enable	Bool	false	Turns on the hue × saturation lattice. Dragging a cell enables it for you.
warp_grid	Text		The lattice itself (JSON), authored by dragging in the Warper palette. Hue across, saturation up.
warp_strength	Float	1.0	Scales the whole lattice — the global mix for the Warper. Negative inverts what you drew.
nr_luma	Float	0.0	How far to smooth brightness noise. Go easy: luma detail is what reads as sharpness.
nr_chroma	Float	0.0	Colour-noise smoothing. Chroma tolerates far more than luma before anyone notices, and a grade amplifies chroma noise first — usually the one to reach for.
nr_threshold	Float	0.06	How different a neighbour may be and still count as a noisy sample of THIS pixel. This is what keeps edges: past it, a neighbour is a different thing, not noise.
nr_radius	Float	2.0	How far the noise reduction looks. Bigger removes coarser grain and costs more.
blur_r	Float	0.0	A blur on the red channel alone, in pixels — softens red noise or a chroma edge without touching detail in the others.
blur_g	Float	0.0	A blur on the green channel alone, in pixels.
blur_b	Float	0.0	A blur on the blue channel alone, in pixels — blue carries most sensor noise, so this is the one that usually earns its keep.
blur_a	Float	0.0	A blur on the alpha alone, in pixels.
disabled	Bool	false	Bypass: the node passes its first input through untouched (D in the graph). The knobs keep their values for when it comes back.
label	Text		A note shown under the node in the graph — what this node is FOR. Never affects the render or the cache.
hide_input	Bool	false	Draw the node without its input wire — a tidy graph for a node whose source is obvious (a Dot, a viewer tap).
