Option to automatically name /color code layers based on the layer's blending mode

[John25002807a5al]

This is something for which I have longed for years... please enable a toggle on/off option to name layers based on the blend mode chosen. Currently, the name of a newly created layer defaults to "layer #", but with this suggested change it would default to "normal mode #", and it would then rename automatically (if enabled) to whatever layer mode it is changed to. For example: if the layer is changed to multiply mode its layer name would automatically change to "multiply#". And also, if enabled, would be to give the layer a unique layer color associated with that mode ( e.g. dissolve is gray, multiply is dark blue, color burn is cyan, ...  overlay is yellow, etc.). Of course, this automatic naming and coloring of layers would be an option that could be disabled, and overwritten by the user. This would be very helpful when quickly interpreting the complex layer stacks that often arise in Photoshop, and especially when merging layers. I have at times accidentally merged layers of varying modes with bad results, thinking they were all "normal". Oops. So, now I do the layer renaming/colorizing manually or using actions I have created, but really, why not make it an embedded option of the program? The default naming method of "layer#" needs advancement. Thanks.

@John25002807a5al – On the layer colouring, there are around x4 the quantity of layer blend modes than the available colours. There is an open feature request that does not have many votes, this is easier said than done (otherwise if trivial, it would have been implemented long ago). 

https://community.adobe.com/t5/photoshop-ecosystem-ideas/p-add-custom-colors-for-colour-coding-layer...

Things to think about:

1) GUI - Would this just be another single icon for "custom", which when selected would then bring up a new window with colour picker? Then click on the custom icon to edit the existing colour values? Vertical real estate in the contextual menu is limited when right-clicking on the layer name, as opposed to the eye icon or thumbnail icon.

2) ACTIONS - How would this be recorded into an action and the underlying code that is generated by the action that would be used in scripting or UXP development?

3) BACKWARDS COMPATIBILITY - what should or would happen when an older version of Photoshop opened a file containing a custom layer colour?

These are of course issues for the developers at Adobe, however, users have to give feedback and offer opinions or they may not like the implementation that Adobe may eventually decide upon.

[Stephen_A_Marsh]

As this is a feature request/idea topic that may never be implemented by Adobe, I can at least help you today with a script. 

This script will only rename layers that meet the default naming criteria of Layer #, such as:

Layer 1

Layer 2

...

Layer 9

Layer 10

etc.

If you change the blend mode of a layer after the script has been run, it will no longer meet the criteria and will not be renamed a second time. The script could be modified.

By default, the script selects all layers. This single line of code could be disabled if you prefer to manually select the layers first.

1. Copy the code text to the clipboard
2. Open a new blank file in a plain-text editor (not in a word processor)
3. Paste the code in
4. Save the text file as .txt
5. Rename the file extension from .txt to .jsx
6. Install or browse to the .jsx file to run:

[jazz-y]

I liked this idea and decided to add functionality to the code of @Stephen_A_Marsh . Now script uses blend mode change events and layer creation events as a trigger to run:

The work of the script is slightly different from the description of @John25002807a5al  because replacing the word "layer" causes certain difficulties:

a) there are groups, content, adjustment layers, etc. which are called differently and this must be taken into account

b) it is necessary to maintain continuous numbering for each type of blending mode, which will greatly complicate the script logic

So I decided to just add the name of the blend mode before the current name. I didn’t have enough colors for each blending mode, so I grouped them as it seemed convenient to me (the color assignment for each type of overlay can be changed - double click on the list).

To store color label settings, script uses the BlendModeLabels.desc file located in the folder %USERPROFILE%\AppData\Roaming\Adobe\Adobe Photoshop current version\Adobe Photoshop current version Settings (windows) , if necessary, it can be copied and used for work with the same settings on several workstations.

UPD: Updated the code. Added the ability to enable/disable tracking of each blending mode (dialog box by double clicking on the list or left clicking on the line)
