Here is my second plugin for Substance Designer: “Frame Colors”. After the first one, “Print Modified Values”, I immediately started with this new utility. The purpose of this plugin is very simple: to quickly change the color of selected frames choosing between various predefined samples in a palette.
⬇️ Download “Frame Colors”
How to install it
Once you have downloaded and unzipped the ZIP file, move the main folder “etr_frame_colors” (which also contains a .json file and another subfolder folder with the same name) to where you normally have other Designer plugins installed.
If you have never done it I recommend you to use this directory:
/Users/NAME/Documents/Adobe/Adobe Substance 3D Designer/python/sduserplugins/
Then start Designer, open Preferences / Projects, click on the vertical tab “User project” (inside Configuration / Project Files) and then on the horizontal tab Python. Click on the little + icon on the right and add the above directory. And as indicated in yellow, once this is done you will have to restart Designer.

Once Designer is restarted, the plugin should be loaded. But just in case, open Tools / Plugin Manager and check that the checkbox of our plugin is enabled. Doing this, by the way, you can activate or deactivate any plugin.

As soon as you install it, you will not see it appear in your top bar. To do this you must first create a new Substance Graph. Do it. Now you will see a new little green frame button appearing in the main toolbar. And this one can enable or disable the big group of color samples immediately below. I recommend to close the Atomic nodes to make room for this (after all, I particularly never add them from here, but using the space bar)

How to use it
It is very simple: select the frame or frames you want to colorise and press any of these small color buttons. You can use a “lasso selection” to select a bunch of frames and also nodes, don’t worry: the plugin will recognise frames, discarding nodes or any other graph element, and will apply the color.
As you can see, default blue is marked with a dot. I recommend to use the first vanish-subtle colors with big frames, the ones that are behind a big group of nodes. And leave the more vivid-strong colors for those frames that are used as a call for attention in some special or important node.
DISCLAIMERS
SHORT: I have done my best to create a stable and robust tool. But use with caution, please. I recommend to create a copy of your graph before proceed to comment your nodes using this tool.
