Se refera la temperatura de culoare. Cel mai bine va uitati la temperatura specificata decat la "adjective".

 

Am gasit un "neutru" pe net de 4500K . Deci undeva intre lumina calda si rece.

Alb rece 5000-6000K, alb neutru ~ 4000K, adica temperatura de culoare in Kelvini.

 

Este referitor la emisia corpului negru... trebuie sa te documentezi.

 

Culorile reci le percepi ca mai albastrui, cele calde ca mai galbui.

Daca complicam si bagam in ecuatie si CRI - in general este mai usor sa se obtina CRI mare/bun la temperaturi de culoare reduse.

Alb neutru aduce a lumină naturală. Albul cald are o lumină gălbuie, similară cu cea a unui bec.

Albul rece are aproximativ temperatura de culoare a soarelui, 6000K, cel cald aproximativ culoarea becului cu halogen, 3000K, iar cel neutru este intermediar. La ochi albul rece pare mai albastru decat soarele, iar albul cald pare mai galben decat becul cu halogen.
