how can I translate 翳红?
楊牧 《十二月十日辭清水灣》
  
  我探首看崖下潮來潮去
  讓記憶擱淺在那裏。正午
  窗子裏空氣虛構一種寧靜
  花瓣無懈可擊，紛紛拋落針織
  刺繡上，暗微的香氣洴澼浮沉
  湧進我多風的心裏
  
  光影在石礁一帶遊戲。遙遠
  水鳥各自東西，隨我的意志
  翻飛，有些在夢的邊緣失落
  有些自動回歸。山勢略顯憂愁
  傾斜若時間之餘韻
  太陽在翳紅與蒼黃間忐忑滑行
  
  By the cliffs, I overlook a tide that comes and goes
  and leave my memory stranded there. At noon
  behind the window the air fabricates tranquillity
  the petals are impeccable, their delicate
  fragrance scattered over the stitching
  floating, rushing down to my goustrous heart
  
  Light and shadow play around the rocks. Further out
  seagulls break from each other, fluttering
  by my grit some are lost at the edge of dreams
  though others return. The ridge seems to dishearten
  it lies aslant like the rests in a temporal cadence
  with care the sun slides from crimson to straw
