I still have my pallet set up the way I did when I first started painting, they are separated into families of color, my yellows on the upper left, reds on the right, greens along the sides, browns on the bottom and indigo in the lower left hand corner. If needed I also have other pallets and other color schemes for different subjects.
If I was to do it now, I might have considered following the color wheel and having the complimentary color on the opposite side, to make it easier to make a neutral grey. If I tried to change it now I would simply be fumbling with it and feeling like I was learning to paint all over again.
Should you change your pallet set up when taking a workshop
Many times people ask me if they should change the set up of their pallet for my workshops, I tell them to use what they have and add to it.
Label your color
To keep track of any new colors your using write the name of the color on a piece of artist tape or along the side with a permanent sharpie marker.
What I am looking for in a Pallet
One with shallow wells so water does not continue to accumulate in the bottom because that really dilute the color. I always add fresh color when painting - about a Lima bean size. I don't like to fill my well with color and let it dry, I like the creamy constancy of new color and there should be a large area in the center where you can do mixing.
