Purple, Violet
noun, の adjective
A purple color is purple. Simple as that!
むらさきいろ
The reading for 紫 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.
彼女はいつも制服の上に紫色のベストを着ている。
She always wears a purple colored vest over her school uniform.
