It's not so many years ago that Ilford were selling colour films in the UK, the films were made for them by Sakura/Konica, I have a roll of E6 Ilfochrome that never got processed.
They'd hoped to build up sales to a point where it was worth their while re-entering the market with their own films, there's a space on the Mobberley site that was earmarked for a possible colour coating facility.
Last time I was in Istanbul which was just under 3 years ago I saw Ilford colour films (C41) on the shelf of the Turkish Ilford importer/distributor, I should have bought a roll but was in a hurry and on my way to the nearby stockist of Ilford LF film (which was just out of date - but OK).
Ilford have some chemists with Colour experience, you only need to look at Patents held by directors, and despite the Swiss arm now being seperate there's still links at some levels. So while they might not want to make colour materials they have the capability.
