Blender QMM is a free Blender 3.00+ add-on that installs a panel named Quick Metal Materials into 3D Viewport > Sidebar > MAT.
Select an object in your view, and click a button to assign that material to it.
Quick Metal Materials
PCOY, MC, MCMC, & HG71
Chaos Metals, Dark Money Metals, Glass Shaders, Matlib VX, & Tutorials
Great, thanks for sharing.

I grabbed your addon long ago, but just gave it another look – Paper and Skin are particularly nice!
Adding and removing nodes from the selected material is a very cool approach. The thumbnail feature also impresses me. I can definitely learn some Python tricks from your code!
I am not the author of the plugin .

I just suggested for your addon.
Ah, thanks. If you run into Wolf & Nathan Craddock, give them my regards! 
Thanks for testing it! I’ll change the Blender Version in the next release.
Speaking of, I’m open to suggestions for future releases.
For example, I’m planning on removing the Alert Popover that says the material already exists, as it’s not really necessary.
Nothing major, just tweaks to the UI. The metals are now in show/hide sub-panels, and the sidebar category has been renamed to QMM.
I also resolved a naming conflict with other shader addons. ( I wonder how many of us gave our gold shader the same shader.gold_operator idname? 
)
Since Blender doesn’t have a Saved Colors option – at least as far as I know 
– I made a pair of add-ons as a way to quickly access my favorite colors.
I don’t plan on expanding these the way I do QMM, so rather than give them their own thread, I’ll post them here.
They do one simple thing: Assign a custom color to a Principled BSDF’s base color.
PCOY creates a Panel named Pantone Color of the Year under 3D Viewport > Sidebar > PCOY.
The colors are sourced from the Pantone website, which is worth checking out for their suggestions of other colors that pair well with these primaries.
I’ve also included a batch of “Extra” colors that are either community reactions to the official PCOY selections, or non-PCOY specialty Pantone selections of note.
MCMC creates a Panel named Mid-Century Modern Colors under 3D Viewport > Sidebar > MCMC.
The colors are sourced from an article on Dwell.com called 7 Paint Colors That Nail the Midcentury Modern Look.
Note - These are two individual add-ons, so they need to be installed as two individual files.
They are both available from the same repo:
blender-pcoy is not loading. I didn’t see an init.py in the folder, may be the reason.
Thanks for all!
PMOY and MCMC are individual addons, so you need to install them individually.
Best bet for download is to grab the latest ZIPs from Releases.
Cool, got it!
Thanks a ga-zillion!
I’ve posted to Github a buttload of useful materials I’ve created or collected from various sources.
I want to emphasize that none of these are my IP, but all samples are cleared, so use them however you like. Go nuts, show nuts.
This repo contains:
47 Materials - I created these Blender materials based on specs provided by Jarrod Hasenjäger’s Material Studies: Metals. (Please feel free to comment on, or even fork and improve any of these.)
32 Materials - Harvested from tutorials and sample files, attributed in the Material names.
908 Materials - A port of the Materials Library files that shipped with the Blender 2.7.2-compatible version of the add-on, but which are missing from the version that ships with current Blender.
Nice set, really handy!
Thanks for sharing your work.
