I've been seeing this small pocket palette by Expeditionary Art on Flickr. www.expeditionaryart.com
I finally ordered one and came in the mail yesterday. It's business card size and very compact.
I had to decided what colors I wanted to use and this is the color chart I came up with. I also bought additional empty pans, so I can switch out colors.
I like the size and that is so light. I'm thinking about buying another pocket palette that I can load with my Schmincke gouache. Now it's time to see how this palette works out in the field.
