This palette accessory and paint storage system keeps oil paint fresh and pliable for weeks at room temperature. A linear paint tray, upon which daubs of paint are placed, is stored inside an airtight tube. Felt wicks mounted inside the end caps hold clove oil, which prevents the oxidation of oil paints. For heavy bodied acrylics, the end caps are mounted with sponge material or silica gel that would be moistened to create a humid environment that prevents acrylics from drying and hardening. When the artist is ready to paint, the paint tray is removed from the storage tube and secured with clips or Velcro to a mixing palette, paint box, or easel. The painter dips into the paint daubs on the tray to mix the desired colors on their palette. When done painting, the paint tray, with the unused paint, is re-inserted into the tube for storage and transport.
