[bash]

Excerpt from the changelog:

0.4.1

  by detecting Screen and erroring before sending any control sequences (Investigate issues w. screen bash/terminal-colorsaurus#16).

0.4.0

• ⚡ Renamed «color scheme» to «color palette».
• ⚡ Removed is_dark_on_light and is_light_on_dark functions. Use color_scheme instead.
• Add new convenience function color_scheme which returns a nice Dark / Light enum.
• Add support for urxvt's rgba: color format.
• Further refined the documentation (more organized terminal list, new terminals tested).
• Improved handling of ambigous color palettes (e.g. when background color is the same as foreground).
• Queries are now terminated with ST (the standard string terminator) instead of BEL (which is an xterm extension).
