Implementations

impl ColorScheme

pub const fn dark() -> Self

Dark theme (default)

pub const fn light() -> Self

Light theme

pub const fn high_contrast() -> Self

High contrast theme (accessibility)

pub const fn monochrome() -> Self

Monochrome theme honoring the NO_COLOR convention: grayscale only — no named hue, no RGB. Structure is carried by weight (bold), glyphs, and gray levels instead of color.

pub fn severity_color(&self, severity: &str) -> Color

Get color for severity level

pub fn severity_bg_tint(&self, severity: &str) -> Color

Get a subtle background tint for severity (used for row highlighting) Subtle row-background tint for a severity, adapted to the active theme.

Dark themes use dark tints; light themes use pale tints so the dark row text stays readable (the previous hardcoded dark tints made light-theme rows unreadable — dark-on-dark).

pub fn change_color(&self, status: &str) -> Color

Get color for change status

pub fn severity_badge_fg(&self, severity: &str) -> Color

Get appropriate foreground color for severity badges Returns light fg for dark backgrounds (critical, high, info) and dark fg for bright backgrounds

pub fn kev(&self) -> Color

Get KEV (Known Exploited Vulnerabilities) badge color Returns a bright red/orange color to indicate active exploitation

pub const fn kev_badge_fg(&self) -> Color

Get KEV badge foreground color

pub fn direct_dep(&self) -> Color

Get direct dependency badge background color (green - easy to fix)

pub fn transitive_dep(&self) -> Color

Get transitive dependency badge background color (gray - harder to fix)

pub const fn change_badge_fg(&self) -> Color

Get appropriate foreground color for change status badges All change colors (green, red, yellow) work best with dark foreground

pub fn badge_fg_for(&self, bg: Color) -> Color

Pick a readable badge foreground for an arbitrary badge background: bright ANSI colors and high-luminance RGB get the dark foreground, everything else the light one.

pub fn license_badge_fg(&self, category: &str) -> Color

Get appropriate foreground color for license category badges

pub const fn chart_palette(&self) -> [Color; 5]

Chart color palette for visualizations
