This term is used when a painting is worked in a number of different media, for example, watercolor, gouache, coloured ink and pastel.

A hue refers to the gradation of color within the optical spectrum, or visible spectrum, of light. “Hue” may also refer to a particular color within this spectrum, as defined by its dominant wavelength, or the central tendency of its combined wavelengths. For example, a light wave with a central tendency within 565-590 nm will be yellow.

Reference from Wikipedia definition of hue.

A watercolour paper with a rough surface which allows the paint to settle in its hollows or recesses. This creates a speckled finish.

Compare with HP and NOT papers.
