Is there any occult/Illuminati or whatever else reason for there being so many depictions of masked people with red Hoods in popular media?
For example the two popular series la Casa de papel and squid game or the character of shy guy that appears in some of the mario games.

Ok. 
QRD on generally practiced robes' colors symbology:
White: follower/participant of the cult
Red: priest/sacrificer of the cult
Black: watchdog/security of the cult
There are many variations and inversions, but as general rule this is it.

Sometimes a variation of black when darker shades of blue.
Sometimes variation of white when lighter shades are used.
