A popular practice of watercolor artists is to fill an empty watercolor travel palette with their own tube colors. This allows the artist to work with their own palette rather than carry around pre-filled colors that they don’t normally use.
I’ve recently learned that there may be a problem with this approach. I’ve seen some information on the internet that suggests tube paints are not the same as pan paints, and that pan paints are formulated differently for the wetting and re-wetting that a travel palette undergoes.
I’ve not been able to find enough information to confirm or deny that claim- yet. For now, I’m still mostly filling empty palettes with my own tube paints. I brought 3 different travel palettes with me this trip with some issues of note.
I’ve been very happy with my American Journey travel palette filled with colors from the Michael Reardon palette, but I have had a problem with the pans popping out from under the metal retaining edge at times. This palette has become easier to handle since the paints have mostly dried. I’ve also stuck each pan down with a wad of Museum putty which was time consuming to do, but seems to work well.
