This vaguely reminds me of "CCSTN" (Color Coded Super Twisted Nematic) LCD displays, which were used in a few Casio calculators to produce basic colour output without the usual RGB colour filter approach.

I noticed an unusual color LCD technology on the Pokémon Pikachu 2 GS too: https://electronics.stackexchange.com/questions/201827/how-d... , https://bulbapedia.bulbagarden.net/wiki/Pok%C3%A9mon_Pikachu...

For some reason I find those displays' shades of orange and green to be SUPER appealing. The blue is nice enough.

I had a feeling the YouTube link would be Posy and was delighted when it was. His videos on display technologies are top notch.
