Apple is reportedly testing a deep red finish for the iPhone 18 Pro and Pro Max, per Bloomberg's Mark Gurman. This would mark the first time the Pro lineup adopts red since the iPhone 14's (PRODUCT)RED editions, though the shade leans toward burgundy rather than vibrant crimson.

Earlier rumors about purple and brown hues for the 18 Pro models are dismissed as variations of the same red concept, suggesting only one red option may launch. Foldable iPhone designs, meanwhile, are expected to prioritize classic space gray/black and silver/white finishes, avoiding bold colors. These updates align with Apple's strategy to differentiate Pro models while maintaining consistency across its foldable line. September 2026 remains the anticipated release window for both devices, with no confirmation on pricing or additional features beyond color options.
