Abstract: An artists' palette that provides air-tight storage for any painting medium. The air-tight palette includes a tray with multiple individual storage wells. Around each well is a trough depression. A cover that fits over each well is attached to the tray in such a manner as to allow pivotal movement about an axis substantially an arc when the cover is opened and closed. When the trough depression is filled with a liquid compatible with the painting medium and the cover is closed and seated in the trough 100% air-tight storage is possible. A secondary means of air-tight storage is provided by an absorbent element inside each cover. When this absorbent element is moistened and the cover is closed the element seats against the top rim of the well and seals against air. This allows the palette to be used without any liquid in the trough. Air-tight storage is also provided by this secondary method.
