• 赤色あかいろCommon
  prenominal modifierLiterally 'red', the color — a common word in that sense. Its political senses (communist, socialist, left-wing) are figurative, much like English 'red'; for 'socialist' it is loose and rarely what you want.

Use 社会主義者 for a socialist as a person; 「ソーシャリスト」 is a less common katakana borrowing of the English word; 赤色 literally means 'red' and covers communist or left-wing loosely rather than socialist in the strict sense.
