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?

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

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.

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/1211...
