col2hex2col 0.3.1

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

• Added 18 new tests for get_color_data()
• Added 8 new tests for create_color_table() (with proper handling of optional gt dependency)
• All 104 tests passing

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)

• Comprehensive input validation for both functions
• Full test coverage with testthat
• Optimized performance using base R instead of tidyverse
• CRAN-ready package structure
