WATERCOLOURS

	WATERCOLOURS

	- Water-colours can basically be defined as water-based trasparent paint in whitch it is the paper that provides the painting with its whites and luminosity. - The same permanent pigments are used as in the production of oil paints. It is bound toghether with a water solution of arabic gum. - The fine pigment particles are trapped in the gaps in the fibres of the paper, where it is fixed thanks to the arabic gum. - It dries through the simple evaporation of the water base. - Water-colour paint that has dried on the palette can, without any problem, be softened up with water to be used again.

CHARACTERISTICS
Color index	defines the pigment independently from the name each manufacturer wishes to give it.
Stability to ligth	tell us the degree of resistance of a point to exposure to direct sun-light.
Coating power	tells us the power of the colour to coat the background it is applied onto.
DIFFERENCES BETWEEN CADMIUM AND "HUE" COLOURS Colors which include the word "Hue" are made with modern alternative pigments. Serie and price are lower.
