I want to know the answer to the following question:
What was the aspect ratio of the NHK Color?
All the background I'm provided with is that "The Nippon Hōsō Kyōkai (NHK, the Japan Broadcasting Corporation) began conducting research to "unlock the fundamental mechanism of video and sound interactions with the five human senses" in 1964, after the Tokyo Olympics.". Is that enough to answer the question?
Answer: no
