This invention provides a reference device for for setting the colour biasing mechanisms on a camera and achieving a consistent colour biasing in different environmental situations, and a method of making the same. The reference device comprises a reflective media having a surface that has had its spectral characteristics analysed and its surface treated with coloured droplets, wherein each of said droplets is less than 5 picolitres in volume, to achieve a degree of desired white neutrality or colour bias of different spectal quality than that which was analyzed as aforesaid. The method for producing a standardized white or colour-biased surface on reflective media for use with a camera with colour balance setting mechanisms, comprises: I) selecting a media with a surface that is suitable for modification to colorimetrically neutral reference surface; ii) analysing the spectral characteristics of the reference surface; treating the surface of the media with coloured droplets, with each of said droplets being less than 5 picolitres in volume to achieve the degree of desired white neutrality or colour bias.
