I noticed in the R3 launch in India on the 11th that they aren't selling the red R3 there at all. I looked up the connotation of the color red in India and found this:
"Red is dynamic and constantly breathing fire in the eyes of the beholder. It incites fear and is the color associated with one of the most revered goddesses in Hindu mythology – Durga. Her fiery image is enhanced by her red tongue and almost red eyes. Red also stands for purity and is the preferred color for a bride’s garment. Red has a deep meaning in the Indian psyche."
So, that doesn't really explain no red R3s in India. From that description, you could go either way on whether red is good or bad, culturally, there.
All of the accessories are made in Indonesia. Not sure why they don't include red in some of their available accessories.
I have noticed that with aftermarket accessories, blue ones are ALL OVER THE COLOR CHART and are the hardest to buy for a Blue R3 for that reason.
Maybe red accessories will be added later.
