😼> Get Mean Color

The counterpart to this pack's RGB Color node: where that one lets you dial in a color by hand, Get Mean Color reads one back out of an actual image. Point it at a region and it tells you, numerically, what color that region averages to.

How it works

Fed a plain image with no mask, it averages every pixel in the frame - which, on anything busy or detailed, tends to land somewhere near a boring mid-gray, because that's what averaging a whole scene usually does. The useful case is with mask_opt connected: mask off just the sky, just a piece of clothing, just a subject's skin, and the average color that comes back actually means something. This pack's own Light Source Mask is a natural feed for it - grab the bright regions of an image, then read their average color, if you want to know roughly what color light is dominating a scene.

There's also an amplify toggle with no further description in the node's own schema, so the honest answer is: flip it and compare. Expect it to push the sampled color further from a washed-out average rather than reading it as-is - but confirm on your own image before relying on it for anything precise.

The inputs and outputs that matter

• image (IMAGE) - required.
• amplify (BOOLEAN, default false) - see above; test it on your own image.
• mask_opt (MASK, optional) - restricts the sampled area; leave it out to average the whole image.
• int (INT) - the packed color value, same format as RGB Color's output.
• red, green, blue (INT each) - the individual channel values.
• hex (STRING) - the color as a hex string, useful anywhere downstream that wants text instead of a packed int.

That's five outputs from one read - pick whichever format the next node in your graph actually wants.

How to install it

Via ComfyUI Manager: search "yanc" or "ComfyUI_yanc" and install, then restart. Manually:

cd ComfyUI/custom_nodes
git clone https://github.com/ALatentPlace/ComfyUI_yanc

then restart ComfyUI. No extra dependencies or model downloads.

Common issues & troubleshooting

The result is a boring, muddy gray. That's what you get averaging an entire unmasked scene - it's not a bug, it's what averaging does. If you want a meaningful color, mask down to a specific region first.

Mask and image resolution mismatch. The usual ComfyUI trap: mask_opt needs to match the image's dimensions, or you'll hit a shape error.

You need a hex string somewhere and only have RGB Color's int. Use this node instead - it's the one in the pack that actually gives you a hex output, RGB Color doesn't.
