In this, which is not a medium for colouring ?

Question

Accepted Answer

The correct option is 2:
Paper is correctly identified as the option that is **not** a medium for colouring because it is classified as the **support** or **ground** in art. The support is the physical material on which the artwork is applied, such as paper, canvas, or wood panel. A colouring medium, conversely, is the substance—like paint, ink, or pastel—that contains the pigment and is used to impart colour onto the support. While paper is an essential part of a watercolour or pastel artwork, its function is to receive the colour, not to be the colour itself.

The incorrect option is 1:
The options of Pastel, Oil Colour, and Water Colour are all distinct and legitimate colouring mediums used by artists. Pastel is a dry medium, typically in stick form, composed almost entirely of pure powdered pigment with just enough binder (like gum tragacanth) to hold its shape, making it a direct source of colour application. Oil Colour (oil paint) is a liquid medium where pigment is suspended in a drying oil, most commonly linseed oil, allowing for slow drying, blending, and deep colour saturation on a support. Water Colour is another liquid medium made of pigment mixed with a water-soluble binder, such as gum arabic; it is designed to be diluted with water and applied to the support, often relying on the luminosity of the paper for light effects. Therefore, since all three are materials used to apply and create colour, they are correctly categorized as colouring mediums.
