Purple
Violet
noun
The kanji and the word are exactly the same. That means they share meanings as well.
The reading is different from the one you learned with the kanji. To remember this reading, think about how the previous village you went to was all purple. It was the "村先" (むらさき) that you went to. Everything. Absolutely everything was purple.
暗闇の中でキラキラ光る紫色の光を見た瞬間、「母だ」と思ったんです。
The instant I saw purple light shining through the darkness, I thought, "Mom."
