Yes — in general, color is considered an intensive property because it does not depend on the amount of substance present. Intensive properties are inherent to the material (e.g., melting point, density, refractive index, color/hue).
Caveats:
- The perceived intensity of color can change with concentration and path length (Beer–Lambert law for solutions): a dilute solution may look pale while a concentrated one looks darker, even though the substance’s intrinsic hue is the same.
- Scattering, particle size, or aggregation (colloids, nanoparticles) can change apparent color.
- If the sample changes composition (reaction, impurity), the color can change because the intrinsic property changed.
So: color (hue) is intensive, but observed color intensity can depend on conditions like concentration and sample thickness.
