color_adjust_HSL_visual

Same dial set as color_adjust_HSL - hue, brightness, contrast, saturation, sharpness, two blur controls, edge and detail enhance - with one difference: this one is marked as an output node, so it renders its result directly on the canvas as you drag sliders. It's filed under Apt_Preset/image/visualize_edit, the pack's bucket for nodes built specifically to be watched while you tune them.

Reach for this over the plain version whenever you're actively dialing in a basic post pass and want to see the effect update live, rather than re-queuing the whole graph to check.

How it works

All ten fields apply standard image-adjustment math globally across the frame. blur and gaussian_blur are two independent blur mechanisms - a small-range one and a much wider gaussian-radius one - that stack if both are nonzero.

The inputs and outputs that matter

• hue (-0.5 to 0.5, default 0) - a rotation fraction, not degrees; 0.5 is roughly a half-turn.
• brightness (-1 to 1, default 0), contrast (-1 to 2, default 1).
• saturation (0-5, default 1) - a wide range; typical "1.5 for a bit more pop" values move less than you'd expect here.
• sharpness (-5 to 5, default 1) - negative blurs, positive sharpens.
• blur (0-16, int) and gaussian_blur (0-1024, float) - two independent blur dials, check both before assuming a softness issue is one setting.
• edge_enhance (0-1) and detail_enhance (true/false).
• image in, IMAGE out, and because this is an output node, it also previews on the node itself.

How to install it

Through ComfyUI Manager: search "ComfyUI-Apt_Preset", install, restart. Manually:

cd ComfyUI/custom_nodes
git clone https://github.com/cardenluo/ComfyUI-Apt_Preset.git

then run install.bat (Windows) or install requirements manually on Linux/Mac, and restart. No model downloads needed.

Common issues & troubleshooting

Saturation barely moves. The 0-5 range is wider than usual - push further than intuition suggests before assuming it's not working.

Softer than expected. Both blur and gaussian_blur stack if left nonzero together; check both, not just one.

Sharpness looks wrong. Negative values blur, positive sharpen - that's the convention this pack uses consistently across its sharpen-style dials.

Don't need the live preview? The plain color_adjust_HSL has the same parameters without the forced output-node behavior - better for burying deep in a longer pipeline.

IMPORT FAILED on the pack. This pack is large and updates frequently; users have reported import failures after some updates. Reinstall via ComfyUI Manager and restart first.
