Color science is a foundation encompassing everything required in understanding the: creation, control, reproduction, metrology (measurement), characteristics, properties, and perception of color and color stimuli. It's the growing body of knowledge which informs research and advances development of color technologies, systems, and applications in a variety of diverse fields. If you work in a field involving color— color science matters a great deal.
Color science is an interdisciplinary science which is not narrowly confined as a branch of one science, but is interwoven with many fields of science. Color science incorporates: physics, chemistry, physiology, and psychology and intersects with specialized scientific fields ranging from spectroscopy to neuroscience and numerous others. Fields of endeavor utilizing color science are very broad in art, industry, and scientific research.
Knowledge and application of color science is fundamental to the design and function of components and systems in your color digital camera, display, printer and other color imaging systems. It is at the core of devices and applications used to measure, manage, and control color production, reproduction, and recording.
As indicated earlier in this thread, as someone who was called a color scientist and drew a paycheck from IBM based on that, I find descriptions like the above overly broad.
I'm not surprised you find the description overly broad given you earlier in the thread said: "If we're going to get technical, I consider color science a branch of psychology" which I personally find neither technical or correct. Color science is much broader in its scope, affect, and meaning.
There are university degree programs offered in Color Science such as those at Rochester Institute of Technology (RIT) in the United States. RIT's overview of their doctoral degree program begins with this description of color science:
Color has been an intense topic of interest for thousands of years. Mathematicians, philosophers, physicists, physiologists, poets, and other disciplines have all contributed to our understanding of color. RIT’s color science Ph.D. program allows you to contribute to knowledge creation and practical application of color science. You will conduct extensive research that encompasses diverse fields and multiple disciplines of science.
As a generalization, color science can be defined as the quantification of our perception of color.
Perception is a function of the brain: https://en.wikipedia.org/wiki/Perception
Its mastery requires a multidisciplinary educational approach encompassing physics, chemistry, physiology, statistics, computer science, neuroscience, and psychology.
Neither of which has much to do with CFA designs in cameras.
Color science is used in the design and control of most man-made colored materials including textiles, coatings, and polymers and to specify such diverse materials as soil and wine.
Again, in camera silicon is not a colored material. The CFA may be regarded as such.
It is used extensively in color reproduction including digital photography, desktop and projection display, and printing. Color science is ubiquitous.
Yes but reproduction of color has much about pigments, light and perception of color.
A camera merely records light in three channels, interpretation of that information into color is done after raw conversion, normally based on color profiles.
But, I have seen some discussion, by Tim Parkin mainly, claiming that the CCD backs used by Phase One and Hasselblad could not correctly render differences in natural greens.
Having a Phase One P45+ back, I may share that conclusion. But what is the color of grass? Perceived color may be different from observable colors. Things may look different under a canopy of greens from same subjects in another surrounding.
I would think that 'hot mirror' design may also play a role. Camera sensors are sensitive to IR, strong filtering near IR may affect reproduction of reds but having weak IR filtering may cause unnatural colors. Some early Leica M models had serious issues with rendering black textiles that have high IR content.
Shooting JPEG, the camera renders the JPG image. That rendition may include a lot of applied color science.
Color profiles in raw processing may involve applied color science, too, but probably less than in camera JPEG.
In camera JPEGs:
- Apply white balance
- Apply tone curves
- Probably apply selective color shifts
- All that may be based on content
