The iPhone 5s and iPhone 5c comes in a multitude of colors, with the iPhone 5s being available in Gold, Space Gray, and Silver, while the iPhone 5c comes in Pink, Yellow, White, Green, and Blue, but which color is the most popular? Well according to a survey conducted by Consumer Intelligence Research Partners, it has been found that the Space Gray finish is the most popular for the iPhone 5s, while Blue is the most popular choice when it comes to the iPhone 5c. This is particularly interesting given that the Gold iPhone 5s was originally report as a hit, especially amongst Chinese customers, but we guess this might not necessarily apply to everyone.The overall popularity of both colors can actually be further split based on gender, which is what the survey has done. They found that men typically favored the Space Gray finish on the iPhone 5s, while women had a slight preference to Silver, while Gold was a somewhat equal split. For the iPhone 5c, white was the most popular choice for men, while women seem to gravitate towards pink. According to CIRP Partner and Co-Founder, Mike Levin, “iPhone 5S and 5C colors seem to confirm some traditional gender biases. In the iPhone 5C, men prefer the neutral white, and the Space Gray in the iPhone 5S. In contrast, women prefer lighter silver 5S and the brighter iPhone 5C colors. Interestingly, no one, including the women in the survey, appears to want the Yellow iPhone 5C very much.”
