What is the difference between tone and mark making in art?

Tone refers to the lightness or darkness of a color, which helps create depth, volume, and mood in a piece of art. Mark making, on the other hand, involves the techniques and styles used to create lines, textures, and patterns, reflecting the artist's hand and emotional expression. While tone contributes to the overall atmosphere and dimensionality of an artwork, mark making focuses on the physicality and individuality of the artist's process. Together, they work to enhance the visual language of a piece.
