This short video provides viewers with an overview and short summary of Colour Standards.
The measurement of colour is now an exact science. This is due to the simultaneous evolution of high-quality instrumentation, and high-quality standards to calibrate and control this instrumentation.
Colour measurement is also a highly sophisticated science and accurate measurement is necessary in almost every industry. Such industries range from the Pharma and Cosmetics industries, right through to both potable and polluted waters, Beverages both alcoholic and non-alcoholic, Food and many other industrial segments.
By way of description of each scale:
ASTM colour standards are used in the determination of colour within petroleum products.
Saybolt colour reference standards are used for process control of products such as edible and industrial oils, fuels, chemicals, pharmaceuticals, paints and coatings.
Gardner Standards, these liquid colour standards range from water white through yellow to deep amber and are generally used to colour test varnishes, oil and resins which have reached colouration through heating.
Platinum Cobalt Standards also called Hazen were first developed as a way to evaluate pollution levels in waste water. They have since expanded to being used as a common method of comparison of the intensity of yellow-tinted samples.
Pharmacopoeia methods for colour assessment of pharmaceutical solutions are based mostly on a visual comparison. Starting with primary colour liquid standards red, yellow and blue, formulated as per the Pharmacopoeia, dilutions and mixtures of these primary colours are made to give colour standards such as brown and green and in turn produce the working standards.
