Same happens in Korean for technically what's green. Most adults will say 'blue light' for signals in a quick response. It really has to do with Chinese characters for blue 청[靑] and green 녹[綠]. When examining the words, they're both describing something that is 푸르다. 푸르다 means something that is related to the clear sky, sea, or the color of grass. Unfortunately, Google Translate just responds that 프르다 simply means blue which it's not. Also my take: Your tongue twists a bit less when saying blue in Korean rather than green. Can lazy reflexes affect language?
