Kaleidoscope add-on is a small package of nodes for Blender. These nodes allow you to make your scene more realistic and accurate to the real world.
The Spectrum Node is designed for providing you with infinite color palettes and manage them directly in Blender. It comes with a ton of rules to generate pleasing palettes. You can even publish your palettes so that users using the add-on can access them. There is even more features, which I have explained in the video.
The Intensity Node is a collection of pre-defined values that can be used to make your materials and lighting more accurate.
Both these nodes can be animated, and have built in syncing functionality to transfer all your saved palettes and values to another system automatically.
Kaleidoscope add-on is completely free to use. To support me in the development of this add-on you can donate while downloading.
