08:52 in Destin's Smarter Every Day's Why Are there Holes in the James Webb Sunshield? (Explained by My Dad) - Smarter Every Day 270 (linked below) Destin's dad Daryl motions to a full scale simulator up of the JWST sunshield and says:
This is the sunny side, this is what the Sun will see, it will be purple like this. This is silicon on this side.
Question: Why is the sunny side of JWST's sunshield purple and covered with silicon?

note: The optical properties of the sunshield in visible light will also be important for answers to:
- How "specularly" and therefore spectacularly will JWST reflect sunlight? Will we be watching for JWST flares?
