There was a post I wanted to comment on (190551) just like an hour ago but it was deleted.
This was the twitter link for the pictures (https://twitter.com/PiocheuRoyaume/status/1343539769532416006).
Attached are more pictures, but they're human profiles.
My idea is from a post on reddit (https://www.reddit.com/r/conspiracytheories/comments/kbxxye/2021s_pantone_colors_of_the_year_are_called/) about Pantone's colors of the year (https://www.pantone.com/color-of-the-year-2021).
From Pantone's Instagram picture,
"Illuminating, a marriage of color conveying a message of strength and hopefulness that is both enduring and uplifting.
Illuminating is a bright and cheerful yellow sparkling with vivacity, a warming yellow shade imbued with solar power.
Ultimate Gray is emblematic of solid and dependable elements which are everlasting and provide a firm foundation.
These two independent colors that come together to create an aspirational color pairing, conjoining deeper feelings of thoughtfulness with the optimistic promise of a sunshine filled day."
The color grey and their mention of the illuminati from the reddit post reminded me of these monochrome profile pictures.
The quote says about "ultimate grey" that they provide a "firm foundation". It's paired with "illuminating yellow" which can be connected to the illuminati or to how Lucifer means "light bearer".
