There is 푸르다 which can refer to green or blue. Specifically “맑은 가을 하늘이나 깊은 바다, 싱싱한 풀의 빛깔과 같이 밝고 선명하다”.

I have no idea what’s up with that article title though. Clearly there is 파랗다/파란색 etc? Edit: the title should be “languages don’t map colors exactly the same and can have more or less words for a color” would be a better title. But I think most people already know that.
