Ming-Chi Kuo predicts that Apple will release this year's iPhones in Silver, Space Gray, Gold, Red, Blue, and Orange.
Ming-Chi Kuo, a reliable analyst, predicts Apple will release the rumored 6.1-inch iPhone in gold, red, blue, orange, gray and white. The other models will probably be released in Space Gray and Silver, and maybe the new Gold color from the iPhone 8 and iPhone 8 Plus.
We expect the demands for the new 6.5" OLED iPhone will be better than iPhone X because of similar or lower price but with larger display, dual-sim dual-standby (DSDS), and three possible casing colors (black, white, and gold).
The new 6.1" LCD iPhone is expected to boost better-replacement demands than iPhone 8/8s did due to being equipped with full-screen, Face ID, selling price lower than $700 USD, DSDS and five possible casing colors (grey, white, blue, red, and orange).
OnLeaks even claims that Apple is prototyping the 2018 iPhones in yellow and pink too.
