Final answer:
Graphite is the most colorfast dry drawing media. Pastels, Conte crayons, and charcoal are not as colorfast.
Step-by-step explanation:
Of the dry drawing media, graphite is the most colorfast.
Graphite is made of carbon and it is a dark gray material that leaves a mark on paper when applied. It produces a range of values from light gray to deep black, depending on the pressure applied while drawing. Graphite has excellent lightfastness, meaning it resists fading or changing color over time.
On the other hand, pastels, Conte crayons, and charcoal are not as colorfast as graphite. Pastels are made of pigment mixed with a binder, and the colors can fade or change due to light exposure. Conte crayons are similar to pastels and are also susceptible to fading. Charcoal, being a carbon-rich material, is prone to smudging and changing over time.
