Gcm 360 | week 2 - colour basics. When you measure a colour we need to know about three things : l* a* b* - object"s colour - human observer, d50 - light source, 2 degrees - human observer. Colour is a perception in our eye-brain visual system that results from light leaving a source, reflecting off an object and arriving at our eye. Wavelengths arriving at the eye are interpreted by our eye-brain visual system and we see colour. eye-brain visual system. The colour red is a sensation in our. To understand colour we need to understand light-object human observer. Light is a small part of the electromagnetic spectrum. The spectrum is expressed in terms of wavelength. Light sources have different amounts of these wavelengths. Light has a huge impact on the colour of an object. Light can be measured using an instrument to determine its spectrum. 4 different ways to specify a light source: spectral graph.
