Differentiate between a chaotic light with a combination of intensities and a reliable light source capable of returning all the colors of the visible spectrum.
Anticipate metamerism problems by comparing the behavior of your lights with your colors. It will also be easy to understand why your blue notebook turns green under a yellow light.
You can choose to display the curves of the same color as the blue you are viewing, set it to a different color, or project the visible spectrum on it.
Explain without effort to your partners the color / light interaction by displaying in front of them the colors and lights freshly measured.
Make the connection between the colors and their corresponding wavelengths.
The intensity peaks of the curves align with certain colors on the spectrum that you will identify at a glance.
