There's a great video on YouTube, I believe from Vox, that explains how the colors became associated with the parties. Short answer: color television and two decades of elections to refine the map.
Red and blue are both primary colors and showed up quite well on early color televisions. It wasn't really until the early 90s that everyone really started associating Republicans with red and Democrats with blue.
Actually there were some networks who used red for Democrats in 84 also.
The footage is on YouTube.
Everyone knows what this was.
A more biased media and Democrat allies insecure of the association with communism lining up to avoid using that color.
