We recommend using the edges of the artists’ pastels for shading. This will achieve more even and defined stroke widths, which adhere better to their background.
Variations in colour intensity
The level of pressure exerted will determine the amount of pigmentation the crayons deposit onto the paper. The artist has a wide range of possibilities, from delicate, fine lines through to impulsive splashes of colour.
Colours can be blended by vigorously superimposing different layers, causing the individual strokes of colour to merge softly into one another.
Pastel pigment can be grated off the crayon using sandpaper. If the surface has been sprayed with a fixative, the coloured pigments will bind to the background. Damp acrylic paints were used in this example.
Adjacent lines of colour can easily be smudged with a finger to create an even surface with a delicate transition of colour.
To create even areas of colour, paint over the strokes made with Polychromos artists’ pastels using a bristle brush and paraffin oil (baby oil or salad oil). This technique is ideal for colouring paper and creating backgrounds and bases.
Pastel colours can be completely removed from smooth, firm types of paper using a vinyl eraser. Dabbing with an art eraser will lighten the colours.
Every fixing process alters the vividness of the colours. The softer the pastel crayon, the greater the need to fix the colour onto the paper. Polychromos artists’ pastel crayons are relatively hard and adhere well to the structure of the paper, meaning that only minimal fixing is required.
