There are many physical factors that influence the way we see the colour of objects, one of which is gloss. When light strikes an object, most of the light enters the object, except for a small amount that is reflected off the object's surface. This reflected light is responsible for the shiny or bright appearance of an object, otherwise known as gloss. Whether or not an object will have a glossy or a matte appearance correlates for the way light is reflected to our eyes. Specular reflection, or a glossy appearance, occurs when there is a mirror-like reflection of light off a smooth surface. When looking at a rougher, more irregular surface, the specular reflection becomes diffuse. This diffuse reflection (or matte appearance) occurs when the light is reflected back at many angles, rather than one mirror-like angle.

Why accurate colour matching needs to control for gloss / Jason Loehr in POLYMERS PAINT COLOUR JOURNAL - PPCJ, Vol. 209, N° 4655 (10/2019)  

[article]  inPOLYMERS PAINT COLOUR JOURNAL - PPCJ > Vol. 209, N° 4655 (10/2019) Titre : Why accurate colour matching needs to control for gloss Type de document : texte imprimé Auteurs : Jason Loehr, Auteur Année de publication : 2019 Langues : Anglais (eng) Catégories : Brillance (optique) -- Mesure Colorimétrie vision des couleurs Index. décimale : 535.6 Couleur Résumé : The author explains what makes gloss and colour management so challenging, how to measure and account for gloss and why it is so important. It's widely recognised that visual colour evaluation can be imprecise. Even under the same lighting conditions, two individuels can still see and describe colour differently due to a variety of physical factors. In order to overcome this, the industry looks to spectrophotometers and specialised software that can accurately match, correct and control colour. Of note, samples with differing gloss levels can present unique challenges for both visual assessment and digital colour management.
