Additive and subtractive color models describe how color is created. They are not competing theories — rather, these models are the two most common and practical ways to create the perception of color. The basis behind these color models lies in breaking the visible light spectrum into its most dominant regions — red, green and blue.

Humans have always been fascinated by light-producing organisms. Biofluorescence and bioluminescence are two naturally occurring phenomena that people can observe in certain creatures that have evolved to produce or emit light. While these capabilities may seem very similar, biofluorescence and bioluminescence have unique characteristics that make them quite distinct from one another. In this post, we will discuss […]

When it comes to the appearance of color, you cannot underestimate the importance of lighting. Yet, lighting can be confusing, as much of the terminology sounds similar but has vastly different meanings.
