I have a document with multiple layers. Each layer consisting of different color pixels. If I access the component channels using the componentChannels property of the document (see below), how do I get a component channel for the entire document? Are the channels for each of the layers merged or added?

This is my document:

This is the component channel for the entire document (for all visible layers).

You can get the average color like this https://community.adobe.com/t5/photoshop-ecosystem-discussions/get-color-from-selected-area/m-p/12113603#M553549

I would merge all visible layers to a new temporary layer, run the blur > average filter and get the colour values before deleting the temporary layer. No need to worry about component or other channels if this is a standard RGB or CMYK mode file with no spot colour channels.

Problem is not to do it in Photoshop. I have to do it in Python. So, I blend/merge all layers, then get the average color from the histogram?

Sorry I can't help with Python. If possible I'd just do it all in Photoshop and return the average value back to Python.

Good luck, hopefully someone else can help.

One thing I forgot to add: I'm looking to get the average color for the entire document.
