Question

Name the tool that is used to smoothly mix two different colours

Answer 1

The tux paint is a drawing program for children, on the computer, in general.

If someone downloads the tux paint version 0.9.22 they are  able to perform acts of drawing and editing.

On the left side there is a tool bar which shows the  commands to be selected from, i.e. the tools to be selected to perform the act  of drawing, coloring, painting, editing, etc.

The middle is the drawing canvas and on the right side is  the selection options.

There are options beside the color palette, which can be  used to mix.
