What is a 'clear' color value? #32

Closed phelps closed 3 years ago

phelps commented 3 years ago

From the Adafruit documentation:

read the color_data property to retrieve the red, green, blue, and clear color values as a 4-tuple of 16-bit values …

I can't, for the life of me, figure out what a "clear" color value or "clear light" refers to! Deep googling yields information about Tibetan Bhuddism and a psychedelic rock band from the 1960s.

Thanks in advance.

full spectral light - you can check the APDS9960 datasheet for spectral range!

I'm not a color expert, but I feel like I understand the basic concept of RGB values. However, it's not clear to me what "full spectral light" means. If anyone is able to explain further, or provide a link to a good article, please share. Thanks.
