Geskin's tweet refers to previous rumors suggesting Apple will offer the "iPhone 8" – as well its companion devices, the iPhone 7s and the iPhone 7s Plus – in silver, gold, and black (not shown).
The three colors were first mentioned in early August by notable KGI Securities analyst Ming-Chi Kuo and appeared to line up with dummy model images that were circulating at the time, albeit with a question mark remaining over the copper-tinged appearance of the gold model, described by the dummy leaker as "champagne gold".
A couple of weeks later, Geskin claimed the internal name for the unusual-looking color was "Blush Gold" and offered his own OLED iPhone render to give an idea of its appearance.
Following today's emergence of sim tray photos, Geskin later shared another comped image offering a comparison of the copper-like tint compared to previous gold iPhone options.
The new color has divided observers, with some calling it the "Zune option", referring to Microsoft's much-maligned brown music player. Still, it's hard to know for sure how the so-called "Blush Gold" color will appear in natural light, if indeed Apple plans to offer it instead of its traditional Rose Gold or Gold colors.
Apple is expected to offer the new iPhones in 64GB, 256GB, and 512GB storage capacities at $999, $1099, and $1199 price points, respectively.
