abyz22_blend_onecolor

Sometimes you don't want a second image to blend with - you want to pour a single color over part of the frame and fade it. That's abyz22_blend_onecolor, the sibling of the pack's abyz22_blendimages. It blends your image with a solid R/G/B fill through a mask, which sounds trivial until you need to tint a cloth region, warm up a shadow area, or push a piece of skin toward a specific tone and want it to stay a number you can tune instead of a guess.

It lives in abyz22/image_control, the Impact-Pack-derived fork that does body editing and outpainting. This node is the utility-grade component: no model, no weights, just a color math pass.

Inputs that matter

• imageA - the image to tint (IMAGE).
• mask - another "mask" that is actually an IMAGE, same convention as abyz22_blendimages. White = color shows, black = original shows, grey = partial. Feed it a feathered mask or the blend edge will look cut with scissors.
• blend_percentage (0–1, default 0.5) - how strongly the color wins where the mask is white.
• R, G, B (each 0–255) - the fill color. Default is 255/255/255, pure white.

Output is a single image. There's no color-picker UI here - the three integer sliders are the entire palette - so for anything more exotic than a flat tint you'll want a color wheel node upstream and this node's simpler sibling instead.

How it works

The code builds a tensor the shape of your image filled with your R/G/B values, then calls WAS Node Suite's "Image Blend by Mask" once per batch frame, exactly like abyz22_blendimages. Which means the same dependency lands on you: WAS Node Suite must be installed, or this node throws at execution when it looks up the node mapping. The pack's own requirements.txt (openpyxl, pytorch-lightning, kornia) won't pull WAS in for you.

Install

Same as every node in this pack:

cd ComfyUI/custom_nodes
git clone https://github.com/abyz22/image_control

or install "image_control" via ComfyUI Manager, then restart. First startup is slow because of the pytorch-lightning dependency.

Where people get burned

The mask-is-an-IMAGE thing again - if you're hooking up a MASK-typed output from a segmentation node, convert it to an image first or the shapes won't line up. Also, blend_percentage above ~0.6 with a pure color tends to read as "painted", because a flat fill has no texture to fall back on; if you're tinting something with detail, keep it around 0.3–0.5 and let the original texture carry through. The classic use in this pack's world is the see-through-clothes trick - blend a skin-tone fill through a garment mask at low strength so the fabric reads as translucent rather than recolored.
