Hello everyone! Glad to be the first here 
I’m sharing a set of utility node about color I made. The package contains a Color Harmony, a Color Palette, and a Hex to RGB and RGB to Hex nodes.
As a picture is worth a thousand words, here some more explanations
You can download the tool in the first link of my artstation post:

There are more or less technical nodes to explore, and the graphs are pretty clean. So take a look if you’re interested!
If you have questions or anything else, feel free to contact me here or on twitter @RebiereRobin
I have some others tools in my folders awaiting me to be finalized so let me know if you like the content! (one is about trimsheet 
)
