If you're responsible for determining the right ambiance and light quality of your application, then you probably already know how important understanding Color Rendering Index (CRI) and Correlated Color Temperature (CCT) is.
Here's the problem: CRI and CCT are anything but easy to understand.
Color Rendering Index is calculated based on how well a light source renders eight specific pastel colors. The theory is if it light renders these colors well, it should render all colors well. CRI is a simple and helpful lighting spec to predict how good the visual output of a lighting product will be.
Correlated Color Temperature (CCT or just color temperature) gauges how yellow or blue light appears. It’s measured in Kelvin and
