I have made the palettes of some masterpieces.
It can be inspiring to study the master's palettes. That is the visible colors in the finished paintings and not the pigments originally used by the artists.
When starting a new painting it can be useful to have a predefined range of colours to avoid starting with a white canvas and a few basic colours.
Let me know if you have a favourite masterpiece that you would like to have the palette from and I will post it on the website.
You can download the palettes free on my website:
