Estimating varying illuminant colours in images
Colour Constancy is the ability to perceive colours independently of varying illumi-nation colour. A human could tell that a white t-shirt was indeed white, even under the presence of blue or red illumination. These illuminant colours would actually make the reflectance colour of the t-shirt bluish …

Taphonomy of pigmentary colours in fossil insects
… to elucidate the taphonomy of pigmentary colours in fossil insects. Decay and tumbling experiments are combined to explore environmental, biological and compositional biases constraining the potential for fossilisation of cuticles in various extant taxa. In addition, the trace elemental …

N-colour separation methods for accurate reproduction of spot colours
In packaging, spot colours are used to print key information like brand logos and elements for which the colour accuracy is critical. The present study investigates methods to aid the accurate reproduction of these spot colours with the n-colour printing process. Typical n-colour printing systems …

Modelling of colour appearance of textured colours and smartphones using CIECAM02
… model, CIECAM02 in 2002, to help to predict colours under various viewing conditions from a colour appearance point of view, which has the accuracy of an averaged observer. In this research, an attempt is made to extend this model to predict colours on mobile telephones, which is not covered …

Colours and other optical properties of binary noble metal-noble metal alloys
… the most significant determinant of noble alloy colours is the width of the d-FS gap near to L. Tarnishing of copper rich alloys has a visually observable and measurable effect only when prolonged over many hours, but a rapidly formed film is probably responsible for an ellipsometrically observed …

The role of culture in children’s sex-typed preferences for colours, toys, and affordances: A systems theory approach
Children’s sex-typed preferences for colours and toys are well-established, and often function as markers of sex-typicality in research on the development of sex-typed behaviour. However, children’s sex-typed colour and toy preferences have not been tested cross-culturally, or in remote …

The determination of Dyers' perceived components of colour difference (depth, brightness and hue) between twp similar colours from theor spectral reflectance values
An algorithm, called the WSF algorithm, was developed which could predict the dyers‟ attributes of colour difference (depth, ΔD, brightness, ΔB, and hue, ΔH*) from the reflectance values of a pair of dyeings, enabling the dyer to take full advantage of colorimetric analysis. The algorithm was based …
