PS Script – add colors to groups of layers

[KHKH]

Hey, I'm currently manually colorizing groups of layers. The first group in the document (viewed from the bottom of the layer stack) is VIOLET. Next BLUE etc. (see: image_1). Below is a list with the order of colors.

1. VIOLET
2. BLUE
3. GREEN
4. YELLOW
5. ORANGE

If there are more than 5 groups in the document, I start adding colors again from the beginning (in a loop).

When I have subgroups, I also give them different colors, starting with the next color that is after the color of the parent group (see: image_2).

Is it possible to do it using a script?

Yes. 

Are you using DOM or AM code? 

What is giving you problems?

[KHKH]

Unfortunately, I'm not a programmer and have no knowledge of scripting. I don't even know what the DOM or AM you are asking about is.

[c.pfaffenbichler]

DOM stands for »Document Object Model«and AM for »Action Manager«, the one is more easily »readable« but the other offers more functionality and often higher speed. 

Your process seems so specific that it seems unlikely you will find an existing Script that performs exactly that.

 There are practically no programmers here, and all of us once had no experience in writing scripts ¯\_(ツ)_/¯

Thank you for script 🙂 And You are right I need to start learning javascript because there is a lot of potential in it and I need scripts more and more. Have a nice day ✌️😀
