🎨 Hue/Sat/Light FX

The fastest way to ruin a sunset is a global hue slider. 🎨 Hue/Sat/Light FX doesn't make you do that: it adjusts hue, saturation, and lightness either globally or targeted at a single color family - Reds, Yellows, Greens, Cyans, Blues, or Magentas - with a smooth gaussian transition so the edge between "adjusted" and "untouched" doesn't look painted on.

How it works. Pick target - Master for everything, or one of the six hue families. Then hue (−180 to 180) rotates the hue of that range, saturation (−100 to 100) and lightness (−100 to 100) shift the other two components. Because the selection is a gaussian window around the target family, bumping "Reds" touches orange and magenta gently too, rather than hard-clipping at an arbitrary boundary. It's the "targeted by hue family" approach that plain hue_rotate in the CSS Filters node can't do.

The colorize mode is the sleeper. Flip colorize on and the node abandons the original hue entirely - it paints the image with a single hue (colorize_hue, 0–360) at a fixed saturation (colorize_saturation, default 25) while keeping the original luminance structure. That's a duotone/tint machine in one toggle: pick a hue, and your image becomes a monochrome-but-tinted version of itself. For look-dev, it's the fastest way to try a "teal and nothing else" treatment before you commit to a real grade.

Dual mode, as usual for this family. It's an emitter: feed image_in and get image out (standalone), or take the fx output as a COLOR_FX descriptor into the Color Pro Receiver to make it one stage in a chain. enabled and label are the standard per-effect controls. Order matters in a chain - an HSL shift after a Channel Mixer sees different colors than before one.

Where people get burned: the ranges are asymmetric on purpose - hue spans 360° of rotation (−180 to 180), while saturation and lightness are ±100. And with target set to a specific family, the sliders affect only that family; the most common "why isn't this working" is checking a greens adjustment while target is still on Master or vice versa. Also, colorize ignores your hue/saturation/lightness sliders and uses colorize_hue/colorize_saturation instead - those are separate controls, easy to mix up.

Install. ComfyUI Manager → search "Orion4D_MetaNode", or clone https://github.com/orion4d/Orion4D_MetaNode into custom_nodes/ and restart. Category: Orion4D_MetaNode/ColorGrading. No extra dependencies.

When your "fix the green cast" turns into "the whole image looks green," this is the node that lets you touch only the greens.
