<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">fainter</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 paler that I've seen before include "rather sickly-looking" , "Less colourful" , "Less dark" , "comparatively anaemic" , "Lighter in colour" .)
