Black and White hidden object game with occasional colored panels/images.

An RPG pixel art game that is mostly in black and white with town building elements. It does have a lot of desaturated colors. These are usually used as accents or to highlight important information.

An ASCII side-scroller with RPG elements with some color but mostly in Black and White. Color is primarily for weapons, enemies, and effects. Grindy with extra features if you like programming.

A turn-based roguelike on a tile grid. This game DOES have color. In fact, it has a LOT of color but many of the early areas are mostly grey rather than Black and White so I say it belongs in the list

Software intended to generate fonts. Mostly in Black and White but uses blue and other colors for a select few buttons.

Mostly in Black and White, it uses other colors to highlight important information. A text based RPG. There isn't really animation and the game describes what happens to you. Very old school.

A visual novel mostly in Black and White. Contains distortion effects and uses other colors like blue and red as accents. Apparently this visual novel ties into an album of the same name.

A Where's Waldo style find the thing game. Black and White but you can alter colors based on finding things. Very short.

A black and white RPG game in the style of older RPGs. A lot of emphasis is on Rock, Paper, Scissors and Groundhog day scenarios. Desperately trying to be quirky. No one cares about your pronouns.

A dark fantasy black and white RTS game. Minimalist and easy to learn but hard to master. Many color sets with animated cutscenes. Three factions but they play mostly the same. Story is a bit vague.
