Constants

ansi16

pub const ansi16 = [16]AnsiRgb{ ... };

Standard ANSI 16-color palette as RGB values.

ansi16_names

pub const ansi16_names = [16][]const u8{ ... };

Names for the ANSI 16-color palette.

ansi88

pub const ansi88 = [88]AnsiRgb{ ... };

Full ANSI 88-color palette as RGB values (comptime-generated). Includes 16 standard colors, 8x8x8 color cube (indices 16-79), and 8 grayscale ramp (indices 80-87).

ansi88_names

pub const ansi88_names = [88][]const u8{ ... };

Names for the ANSI 88-color palette.

ansi256

pub const ansi256 = [256]AnsiRgb{ ... };

Full ANSI 256-color palette as RGB values (comptime-generated).

Types

AnsiRgb

pub const AnsiRgb = struct {
    r: u8,
    g: u8,
    b: u8,
};

Functions

rgb6

pub fn rgb6(r: u8, g: u8, b: u8) struct { index: u8 }

Creates an ANSI 256 color from 6x6x6 RGB cube coordinates.

• r, g, b must be in range 0-5
• Returns the ANSI 256 index (16-231)

rgb8

pub fn rgb8(r: u8, g: u8, b: u8) struct { index: u8 }

Creates an ANSI 88 color from 8x8x8 RGB cube coordinates.

• r, g, b must be in range 0-7
• Returns the ANSI 88 index (16-79)

gray

pub fn gray(level: u8) struct { index: u8 }

Creates an ANSI 256 grayscale color.

• level must be in range 0-23 (maps to indices 232-255)
• Returns the ANSI 256 index

gray88

pub fn gray88(level: u8) struct { index: u8 }

Creates an ANSI 88 grayscale color.

• level must be in range 0-7 (maps to indices 80-87)
• Returns the ANSI 88 index

ramp

pub fn ramp(start: RgbColor, end: RgbColor, steps: u8) [256]RgbColor

Generates a linear color interpolation between two colors.

gradient

pub fn gradient(c1: RgbColor, c2: RgbColor, c3: RgbColor, steps: u8) [256]RgbColor

Generates a three-color gradient.

multiGradient

pub fn multiGradient(stops: []const RgbColor, steps: u8) [256]RgbColor

Generates a multi-stop gradient between an array of color stops. Interpolates linearly between consecutive stops.

hueGradient

pub fn hueGradient(steps: u8) [256]RgbColor

Generates a rainbow gradient by rotating through the full hue range in HSL space.

colorWheel

pub fn colorWheel(steps: u8) [256]RgbColor

Generates a full hue rainbow.

Palette Subsets

pub const warm_palette = [8]RgbColor{ ... };

8 warm colors (reds, oranges, yellows).

cool_palette

pub const cool_palette = [8]RgbColor{ ... };

8 cool colors (blues, cyans, teals).

earth_palette

pub const earth_palette = [8]RgbColor{ ... };

8 earth tones (browns, tans).

pastel_palette

pub const pastel_palette = [8]RgbColor{ ... };

8 pastel colors.

neon_palette

pub const neon_palette = [8]RgbColor{ ... };

8 neon/bright colors.
