Visual Style
Caves of Qud employs a restricted “low-res” visual aesthetic that complements its history-focused themes by referencing and paying homage to hardware and software of the past.
Graphics
In-game screens display vignetting and visual scan lines, which give the impression that the game is being viewed through an older style of computer terminal. (Either or both of these effects can be disabled from the options menu.)
Each game zone (or console screen) is 80 tiles (or characters) wide by 25 tall. Each tile is 16 pixels wide by 24 pixels tall and may contain up to three of the game's 18 fixed colors, referred to as the primary, detail, and background colors. Usually the background is left black (the color referred to in the game code as k, and fanonically called “Qud viridian”; see the Palette section). The tiles may be scaled to fit the actual size of the game window.
Exceptions
Some tiles use colors outside of the fixed palette. These colors are always some mixture of the primary and detail colors of the tile. (See Modding:Tiles#4th Color for details.)
Game mods are allowed to specify that their tiles are of sizes other than 16 by 24, however the base game itself doesn't use this function. (See Modding:Tiles#Tile_Size for details.)

Trivia
 |
Caution: This article or section contains unverified speculation and should not be considered canonical. |
- The game code's tendency to refer to object sprites as “tiles” may be an allusion to the phrase “tileset“ as it is used in roguelike circles to refer to optional graphics for a game that can be used in place of the usual text terminal. Unlike some such games, Caves of Qud's tiles mode is enabled by default.
