Colour

The colour of a timber, which is important from a practical point of view, because it may enhance or detract from the decorative value of timber, is caused largely by infiltrates in the cell wall. These may be affected by light, air, or heat causing the colour of the timber to change over a period of time. They may also interact with other materials, as for instance when oak reacts with iron a marked colour change may be induced. The infiltrates and cell contents of some timbers may, during planing, sawing, sanding and so forth, cause irritation of mucous membranes or dermatitis which may in some cases be severe. Mansonia, makore and teak are particular examples of timbers that may elicit a more severe adverse reaction. In other cases a distinctive odour or taste may render a timber particularly suitable or particularly unsuitable for a given application.
