Value is how light or dark a color is. Traditional shading and blending with pencil can create different values. But what happens when you try to create value with a pen or marker? Artists can use hatching (diagonal lines), cross hatching (crisscrossing diagonal lines), and stippling (small dots), among others, to create value in pen or marker.
The closer the lines or dots, the darker the value — the farther away, the lighter the value.
Can you make value scales by hatching, cross hatching and stippling with marker and/or pen?
