Frequently Asked Questions
Color constancy refers to our ability to perceive the consistent color of an object despite changes in lighting conditions. Our brain adapts to different lighting environments, ensuring that we perceive objects with consistent colors, highlighting the remarkable flexibility and stability of our color perception algorithm.
The opponent process theory explains how our brains process and interpret colors in pairs of opposing channels: red vs. green, blue vs. yellow, and black vs. white. When one color in a pair is activated, the other is suppressed, contributing to the richness of our visual experiences.
While color perception has a biological basis, cultural and linguistic influences play a significant role in shaping how we perceive and categorize colors. Different languages may have varying numbers of color terms, and cultural experiences can affect how we interpret and describe colors, exemplified by the unique case of the Himba tribe.
Some African tribes, such as the Himba tribe in Namibia, have been found to have a significantly different perception of color compared to Western cultures. The Himba language only has five basic color terms, which are different from the typical spectrum of color terms in English. The Himba language has more terms describing different shades of green, where blue and green are grouped together under the same term. This “limited” color vocabulary affects how the Himba perceive and categorize colors making it harder for the Himbas to differentiate between the colors that we perceive completely different from one another.

The trichromatic theory proposes that our eyes have three types of photoreceptors, sensitive to red, green, and blue wavelengths of light. By combining the signals from these cones, our brain can perceive a vast spectrum of colors, forming the basis of our color perception.
Cones are responsible for color vision and function best in well-lit conditions, allowing us to see vibrant colors. In contrast, rods excel in low-light environments, providing us with monochromatic vision. The distribution of cones and rods in the retina shapes our ability to perceive colors under different lighting conditions.

Color correction in video production refers to the process of adjusting the colors, exposure, contrast, and other visual elements of a video to achieve a desired look and improve its overall quality. It involves correcting any color irregularities, balancing tones, and ensuring accurate representation of colors.
Color grading is the process of stylizing and enhancing the colors of a video to create a specific look or mood. It involves applying creative adjustments to the hue, saturation, and brightness of different elements in the video. While color correction focuses on correcting colors and achieving natural representation, color grading focuses on artistic and creative enhancements.
A film and video colorist’s services include color correction, color grading, creating consistent looks, and collaborating with filmmakers to achieve the desired visual style and emotional impact for the project. Their work is essential in enhancing the overall quality and aesthetics of the film, making them a vital part of the post-production process.
