Changes in version 1.0.0 (2026-06-18)                  

  - First stable release.

  - nd_informal_tints provides six informal soft backgrounds (not Notre
    Dame brand colors), from the lightest tint to the warmest soft
    yellow: faint_white (#fdfcfa), soft_white (#faf7f1), faint_yellow
    (#fefdf3), soft_yellow_light (#fdf9e6), soft_yellow (#faf3d7), and
    soft_yellow_warm (#f6edc6). The two faint_* tints sit just off pure
    white (CIE L* about 99) for the lightest touch.

  - The "nd" data palette holds Metallic Gold at the sixth position,
    after Dark Sky Blue, so the two golds (Bright Gold and Metallic
    Gold) are not paired until a plot has six or more groups.

  - The colorblind palette is now built from Notre Dame's own colors.
    The borrowed Okabe-Ito palette has been removed (palette =
    "okabe_ito" no longer resolves) and replaced by palette = "nd_cvd"
    (aliases "colorblind", "cvd"): a colorblind-friendly ordering of the
    actual Notre Dame colors, derived by a greedy search that maximizes
    the worst-case CIE-Lab Delta-E across simulated deuteranopia,
    protanopia, and tritanopia. The ten anchors stay distinguishable for
    two through ten categories and lead with the CVD-safe ND Blue +
    Bright Gold pair. nd_palettes is now nd, nd_cvd, and former.

  - scale_color_nd(), scale_fill_nd(), and scale_colour_nd() gain a
    palette argument, so the colorblind-friendly or former palettes
    apply to a plot the same way as the default, e.g.
    scale_color_nd(palette = "nd_cvd").

  - nd_colors now catalogs three additional current secondary brand
    colors from the University palette: Medium Blue (#143865), Dark Gold
    (#8c7535), and Light Green (#b3dac5), reachable with nd_color(). The
    full set of official colors on the University branding page is now
    represented. nd_colors also gains a description column: a short
    plain-language note on each color's tier and hue. It is most useful
    for the seven former colors, whose keys give the hue but not the
    tier — six were former secondary colors and purple was the lone
    former tertiary color.

  - The R Markdown stylesheet (nd_css()) now uses Warm White (#efe9d9)
    as the page background instead of a near-white, for a softer page.

  - nd_css() gains a web_fonts argument. nd_css(web_fonts = TRUE) adds a
    Google Fonts import for two open-source typefaces close in feel to
    the brand fonts (Montserrat for body text, Zilla Slab for headings);
    the default stays offline with a system font stack.

  - The main vignette now opens with a quick start covering every
    workflow the easy way --- ggplot2, base R graphics, R Markdown, and
    Shiny --- so the default colors are one step away with no manual
    color picking. It also adds a base R graphics section, a section on
    mixing in a color from outside the palette, and a section on theming
    R Markdown reports.

  - New vignette Theming a Shiny app with NDPalette, plus two runnable
    example apps under inst/examples/: nd-shiny-app (a palette explorer)
    and nd-smd-app (the book's Standardized Mean Difference app, rebuilt
    on the DMAR package and themed with NDPalette; running it needs
    DMAR).

                        Changes in version 0.1.0                        

  - Initial version.

  - nd_palette() returns colors from the Notre Dame brand palette ("nd",
    the default), the Okabe-Ito colorblind-safe palette ("okabe_ito"),
    or the seven former Notre Dame brand colors ("former"). The "nd"
    palette leads with six Notre Dame brand colors that read clearly on
    a white background (navy, bright gold, green, bright blue, metallic
    gold, and dark sky blue) and extends through the seven former Notre
    Dame brand colors, thirteen anchors in all, interpolating beyond
    thirteen. The warm whites and the medium and light sky-blue tints
    are excluded and never emitted.

  - ggplot2 scales scale_color_nd(), scale_fill_nd(), and the
    British-spelling alias scale_colour_nd() apply the "nd" palette to
    the colour and fill aesthetics.

  - show_palette() draws a row of color swatches to preview any palette,
    defaulting to the full Notre Dame set. Swatches can be labeled with
    their hexadecimal values (the default), left unlabeled, or labeled
    with readable names passed as a character vector.

  - nd_palettes, a named list of the three fixed anchor palettes
    (thirteen Notre Dame colors, eight Okabe-Ito colors, and the seven
    former Notre Dame colors), is exported for tools and users that want
    the raw hexadecimal anchors.

  - nd_colors, a data frame cataloging every Notre Dame color the
    package knows about with its brand (University or Athletics) and
    role (primary, secondary, former, tint, or neutral), is exported as
    a reference, and nd_color() looks up hex values from it by name or
    by role. The Athletics colors (a shared blue, the dome golds, and
    Irish Green) are reference only and never enter nd_palette() or the
    scales.

  - nd_tints, a named vector of the four near-white Notre Dame brand
    tints (warm white, light warm white, medium sky blue, and light sky
    blue), is exported for backgrounds, fills, and the light end of
    sequential brand ramps. These tints are too light to read as data
    colors on white and are never returned by nd_palette().

  - nd_css() builds a Notre Dame R Markdown stylesheet from the package
    colors, so an HTML report and its plots carry one brand palette and
    cannot drift apart. nd_css_path() returns the copy shipped with the
    package (for the YAML css field), and html_nd_document() is an R
    Markdown output format that applies it.
