The drawing opposite shows two tone rendering. A suitable colour is chosen and two sides of the cube are shaded - one slightly darker than the other. 2. This drawing shows three tone rendering. this is very similar to the previous example except three shades of the same colour are used 3. Three tone rendering has been used again but in this case a lighting effect has been added to the top. Light is shown reflected on the top part of the cube. This is achieved by shading in a radial pattern. The coloured pencil follows the ‘invisible’ red guidelines. As the rendering progresses from right to left more weight is applied to the pencil giving a darker shade

4. The example opposite shows the lighting effect applied to all three visible sides of the cube. However, to speed up the technique the rendering is not radial but linear (shading is in straight lines). When shading a side of a cube using this technique, a coloured pencil is used in a linear fashion parallel to an edge of the cube 5. Shading: The techniques used above can be adapted. Instead of rendering the sides of the cube - the same colours are used but the colour process is speeded up by drawing lines parallel to the sides. You may notice that the darker lines are close together whilst the lighter lines have a gap between them. This is a quick way of adding limited colour to a drawing.
