The spelling of the word "discolour" can be explained through its International Phonetic Alphabet (IPA) transcription: /dɪsˈkʌlə/. The "dis-" prefix means "not" or "opposite of", while the "colour" root refers to a property of light. The "c" in "colour" is changed to "s" when the suffix "-our" is removed to form "discolour". This spelling is used in British English, while in American English, the spelling "discolor" without the extra "u" is preferred.
The term "discolour" refers to the process or act of causing something to lose its natural or original color, or to become discolored. It involves altering the hue, shade, or tone of an object or substance, resulting in a change that is visually noticeable. Discolouration frequently occurs due to various factors such as exposure to light, heat, chemicals, or the deterioration of materials over time.
To discolour something can happen in various ways, including the occurrence of stains, fading, or the appearance of patches that differ in color from the original surface. This alteration may affect both natural and manufactured items, including fabrics, paints, metals, plastics, and even bodily tissues. For instance, exposure to sunlight can discolour a fabric by causing the fading of its dye and the loss of its vibrant appearance, resulting in a perceptible change in color and tone.
Discolouration can also be a symptom of certain diseases or health conditions, such as jaundice, where the skin and eyes acquire a yellowish or pale color due to liver dysfunction. It is worth noting that discolouration can be reversible or irreversible depending on the cause and the extent of the change. Countermeasures against discolouration involve preventive actions, such as avoiding exposure to damaging agents, using protective coatings or treatments, or employing proper cleaning and maintenance practices to prevent or slow down the process.
To stain; to tinge; to alter the natural hue or colour of; to alter the complexion.

The word discolour originated from Middle English in the 14th century. It is derived from the Old French word descolurer, which means to change color. The Old French term itself is a combination of des- (meaning away or apart) and colur (meaning color). Therefore, the word discolour essentially means to change or remove color.
