Additive vs. Subtractive Color Models

Posted on November 18, 2020 by Ken Phillips

Humans have always been fascinated by light-producing organisms.

Luminance vs. Illuminance: What’s the Difference?

Posted on November 4, 2020 by Ken Phillips

When it comes to the appearance of color, you cannot underestimate the importance of lighting.

Posted on August 6, 2020 by Ken Phillips

Spectrophotometer vs. Colorimeter: What’s the Difference?

What Is Color, and How Do We See Color?

Posted on July 28, 2020 by Ken Phillips

Every object we see has color, and it is an essential part of how we interpret the world. But color isn’t an inherent quality of the objects in front of us. Consider a classic red apple. If you look at it under a blue-tinted light, it will appear somewhat blue, and if you look at […]
