The present study is focused on analysing the change of colours of anodized titanium and effects of applied electrolytic voltages on chromatics. The titanium specimens were anodized in 20 g/L citric acid and 20 g/L baking soda electrolyte by use of different voltages. The colours of anodized titanium were measured with a spectrophotometer and then evaluated in the CIELAB colour space. It is found that different volt produces different colours. Anodizing in the range of 15 V to 150 V produces respectively a wide spectrum of colour ranging from brown to fuchsia. It can be concluded that the colours of the anodized titanium are dependent upon the applied voltages.
