col2hex2col 0.5.2

Bug Fixes

  • Fixed color count test to use >= threshold instead of exact count, preventing test failures when the color database is updated
  • Fixed test warning for 8-digit hex codes triggering fallback

Data

  • Updated color database with 29 new colors from the color-names repository

Documentation

  • Replaced hardcoded “32,462” color count with “32,000+” throughout docs and README
  • Fixed update-colors GitHub Actions workflow (dependency installation, caching, permissions)

col2hex2col 0.5.1

Documentation

  • Updated README examples to show LAB columns in get_color_data() output
  • Added note about LAB columns requiring the farver package
  • Updated contributor information in pkgdown configuration
  • Cleaned up repository structure (moved dev files to .dev/ folder)

col2hex2col 0.5.0

Enhancements

  • create_color_table(): Enhanced column labeling
    • LAB columns now display as “Lab L”, “Lab a”, “Lab b” instead of raw column names
    • First column is automatically labeled “Color Name” regardless of input column name

Bug Fixes

Documentation

  • Updated documentation examples with correct output

col2hex2col 0.4.0

New Features

  • hex_to_color(): Added nearest color fallback functionality
    • When no exact match exists, returns the closest named color using LAB color distance
    • Requires optional farver package for color distance calculations
    • New fallback_nearest_color parameter (default: TRUE) to enable/disable fallback
    • New fallback_distance parameter to get the LAB distance to the matched color

Contributors

  • Added Yann Cohen (@iamYannC) as contributor for the fallback functionality

col2hex2col 0.3.1

CRAN release: 2026-01-21

Enhancements

  • hex_to_color(): Now accepts 8-digit hex codes with alpha channel
    • Automatically strips alpha channel from #RRGGBBAA format codes
    • Maintains backward compatibility with 6-digit #RRGGBB format
    • Works seamlessly with paletteer and other packages that output colors with transparency

Testing

  • Added 7 new tests for 8-digit hex code support in hex_to_color()
  • All 111 tests passing

col2hex2col 0.3.0

New Features

  • get_color_data(): New function to export the complete color database as a data frame
    • Returns all 32,462 color names with their hex codes
    • Data frame format makes it easy to explore, filter, and analyze colors
    • Sorted alphabetically by color name
    • Perfect for creating custom color palettes or searching for specific colors
  • create_color_table(): New function to create visual color swatch tables
    • Displays colors with names, hex codes, and visual color swatches
    • Uses the gt package for beautiful formatted tables
    • Works seamlessly with get_color_data() output
    • Optional dependency - only requires gt if you want to use this feature

Dependencies

  • Added gt to Suggests (optional dependency for create_color_table())
  • Package maintains zero hard dependencies - pure base R for core functions

Testing

col2hex2col 0.2.0

Major Features

  • Extended Color Database: Package now supports over 32,000 color names!
    • 657 R built-in colors (backward compatible)
    • 31,852 colors from the color-names database (MIT license)
    • Total: 32,462 unique color names, 32,161 unique hex codes
  • Enhanced color_to_hex(): Now accepts color names from the extended database
    • Case-insensitive matching (“red”, “Red”, “RED” all work)
    • Whitespace trimming
    • Examples: “sunset orange”, “arctic ocean”, “forest green”
  • Enhanced hex_to_color(): Intelligently selects color names with prioritization
    • R colors are always prioritized when available
    • For non-R colors, returns the shortest available name
    • Significantly increased hex code coverage (from ~650 to 32,161)

Breaking Changes

  • None - fully backward compatible with v0.1.x
  • All existing code using R colors will work unchanged
  • R colors are prioritized in all lookups

Performance Improvements

  • Replaced dynamic color lookup with pre-built internal databases
  • Removed dependency on grDevices functions for lookups
  • Fast constant-time lookup using named vectors stored in R/sysdata.rda

Documentation

  • Updated all function documentation to reflect extended database
  • Added examples using extended color names
  • Updated package description and README
  • Enhanced package-level documentation with key features

Testing

  • Added 22 new tests for extended color functionality
  • All 67 tests passing
  • Tests cover backward compatibility, case insensitivity, and extended colors

Internal Changes

  • Added data-raw/prepare_colornames.R script for data preparation
  • Internal data stored in R/sysdata.rda (~650KB)
  • Removed grDevices from Imports (no longer needed)
