The decorative palettes of the late 4th millennium BCE appear to have lost this function and became commemorative, ornamental, and possibly ceremonial.
The fish zoomorphic palette often had an upper-centrally formed hole, presumably for suspension, and thus display.
The first palettes used in the Badarian Period and in Naqada I were usually plain, rhomboidal or rectangular in shape, without any further decoration.
On these examples there is more focus on symbolism and display, rather than a purely functional object for grinding pigments.
The importance of symbolism eventually outweighs the functional aspect with the more elite examples found in the Naqada III period, but there is also a reversion to non-zoomorphic designs among non-elite individuals.
