Answer :
A painter uses a palette to mix and hold paints. Easels support canvases but are not for mixing, and tusche is a lithographic material, not a tool for holding or mixing paint.
The tool that a painter would use to mix and hold paints while creating a work of art is called a palette. An easel is a support structure used to hold the canvas, but it is not used for mixing paint. The term tusche refers to a black liquid used in lithography for drawing and painting, but not for holding or mixing paints. In the history of painting, the transportability of paints and ease of painting outdoors were greatly facilitated by the invention of the paint tube in 1841 by John Goffe Rand. Prior to that, the primary method of storing mixed paint was in a pig's bladder or glass jars, which were not practical for painting outside the studio.
