I wish to convert a color string to hex value in tikz.

documentclass[border=1mm]{standalone}

usepackage{tikz}

begin{document}

begin{tikzpicture}

tikzset{box/.style={draw,outer sep=0,minimum size=1cm}}

defdy{1}

foreach col [count=i] in {red,orange,yellow,green,cyan,blue,purple} {

    defmycol{col!40!gray}

    node[box,yshift=1cm*i*dy,fill=mycol,label=left:mycol] (main) {ABC};

}

end{tikzpicture}

end{document}

So I wish show red!40!grey to something like #xxxxxxxx but not show how can do such convert!

  @StevenB.Segletes Your answer is definitely a great step towards a solution but does it also work if the colors are defined in the way the OP does? If so, your answer may also be mentioned under this answer.
