I have had the honor of photographing the palettes of two painters in the recent weeks. One is Morgan Walker who has a rich, packed, muted palette:
The other is Trude Parkinson who has a lighter, brighter, more sparse palette.
You can see more of Trude's work at her website:
Both Trude Parkinson and Morgan Walker are wonderful painters!
There are more images of their palettes in my photography gallery in this website:
