Well, some combination of yellow mixed with an organic compound that absorbs UV light bandwidths. There are plenty of organic dyes that absorb in that region (UV). I used to work with them in Advanced Photochemistry Research as an undergraduate.
Machina Dynamica New Dark Matter CD and Blu Ray tray treatment?
This is a set of adhesive-backed thin plastic pieces that one attaches to one’s transport or player disc tray. The disk rests on them during non-spin mode, but presumably don’t touch the applied thin pieces during playback mode. The company says the new Dark Matter pieces reduces background scattered light from reaching the photodetector, thereby improving performance.

The violet / UV sensitive stuff is not phytochromes. ”Phytochromes are a class of photoreceptor in plants, bacteria and fungi use to detect light. They are sensitive to light in the red and far-red region of the visible spectrum and can be classed as either Type I, which are activated by far-red light, or Type II that are activated by red light.[2] Other plant photoreceptors include cryptochromes and phototropins, which respond to blueand ultraviolet-A light and UVR8, which is sensitive to ultraviolet-B light.“ |
