I love tubes but use way too much, filling pans however from tubes, seems to work for me. And your ready to go with less mess or leads to loose or leave behind 🙂

I’m assuming by trays you mean a special watercolor box?
In my experience the specially made boxes are most helpful if you’re in the habit of making up custom mixes that get repeated over several pictures. If you don’t mix up paint much, or if you clean up your mixes every time, the special box adds very little.

I always use tubes – for painting at the studio and for painting outside. For plein air painting I’ve tried several palettes and my fave is the Airtight PEEL-OFF Paint Palette. It’s easy to take it with you and you’ve a large mixing area.
