<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">neutral hue</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 ecru that I've seen before include "off-white" , "one of the colours" , "Light fawn colour" , "Neutral colour" , "Find a cure, strangely, in the colour" .)
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">neutral hue</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for gray that I've seen before include "(Churchyard) Elegy poet" , "a bit gloomy for the Americans" , "An Anatomist; an Elegist" , "dull for Americans" , "Author of ballad opera" .)
