<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">the color of silence?</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for golden that I've seen before include "Most favourable; bright" , "Colour of the fleece sought by Jason" , "In Woodstock we are this" , "- - handshake" , "'The silver apples of the moon / the . . . . . . apples of the sun' (Yeats)" .)
