Elcometer Colour Testing

Elcometer 6210 RAL Colour Charts

A material’s ability to absorb certain wavelengths of light and reflect others is defined as its colour. For example a black material reflects no light across the complete colour spectrum. A pure white material reflects all of the light, whilst all other colours reflect light at different points of the spectrum. 

Colour is quantified by the material’s Red, Green and Blue (RGB) values.
