`M-x list-colors-display` fails with an error. I produced this bug report in Emacs 27.2.2 with no additional packages loaded. I also tried with Emacs 26.3, with the same result. The error is caused by `(apply 'max color-values)` being called when `color-values` is null. Debugger backtrace follows: Debugger entered--Lisp error: (wrong-number-of-arguments # 0) max() apply(max nil) list-colors-print((("LightGreen") ("DarkRed") ("DarkMagenta") ("DarkCyan") ("DarkBlue") ("DarkGray" "DarkGrey") ("grey100") ("grey99") ("grey98") ("grey97") ("grey96") ("grey95") ("grey94") ("grey93") ("grey92") ("grey91") ("grey90") ("grey89") ("grey88") ("gray85") ("grey84" "gray84") ("grey83" "gray83") ("grey82" "gray82") ("grey81" "gray81") ("grey80" "gray80") ("grey79" "gray79") ("grey78" "gray78") ("grey77" "gray77") ("grey76" "gray76") ("grey75" "gray75") ("grey74" "gray74") ("grey73" "gray73") ("grey72" "gray72") ("grey71" "gray71") ("grey70" "gray70") ("grey69" "gray69") ("grey68" "gray68") ("grey67" "gray67") ("grey66" "gray66") ("grey65" "gray65") ("grey64" "gray64") ("grey63" "gray63") ("grey62" "gray62") ("grey61" "gray61") ("grey60" "gray60") ("grey59" "gray59") ("grey58" "gray58") ("grey57" "gray57") ("grey56" "gray56") ("grey55" "gray55") ...) nil) list-colors-display() funcall-interactively(list-colors-display) call-interactively(list-colors-display record nil) command-execute(list-colors-display record) execute-extended-command(nil "list-colors-display" "list-colors-d") funcall-interactively(execute-extended-command nil "list-colors-display" "list-colors-d") call-interactively(execute-extended-command nil nil) command-execute(execute-extended-command) In GNU Emacs 27.2 (build 1, x86_64-apple-darwin18.7.0, NS appkit-1671.60 Version 10.14.6 (Build 18G95)) of 2021-03-27 built on builder10-14.porkrind.org Windowing system distributor 'Apple', version 10.3.1894 System Description: Mac OS X 10.15.7 Recent messages: Unable to load color "grey85" [2 times] For information about GNU Emacs and the GNU system, type C-h C-a.
