How to detect the colour of an iPhone 5c? [duplicate]

Question

After iPhone 5c announcement, i'm curious if anybody knows an API how to get an iPhone 5c colour? I'm sure everyone will find it convenient loading a corresponding UI colour scheme to the device colour.

I'm thinking about wrapping it in something like the UIDevice category, which will return a UIColor.

Update: @ColinE and @Ortwin Gentz has indicated the availability of private UIDevice instance method calls for it.

Please note, that in case of iPhone 5c, what you are really looking for is deviceEnclosureColor, as deviceColor will always return #3b3b3c, as it is a front colour.

method signature:

-(id)_deviceInfoForKey:(struct __CFString { }*)arg1 

UIDevice category for it:

@interface UIDevice (deviceColour)  - (id)_deviceInfoForKey:(struct __CFString { }*)arg1; - (NSString*)deviceColourString_UntilAppleMakesItPublic; - (NSString*)deviceEnclosureColour_UntilAppleMakesItPublic;   @end  @implementation UIDevice (deviceColour)  - (NSString*)deviceColourString_UntilAppleMakesItPublic {     return [self _deviceInfoForKey:@"DeviceColor"]; }  - (NSString*)deviceEnclosureColour_UntilAppleMakesItPublic {     return [self _deviceInfoForKey:@"DeviceEnclosureColor"]; }   @end

The device colour (used to?) be encoded in the serial number of the device. I don't have a device to test on with them not officially released yet, but I imagine the solution will be similar to this:

Typical format of the iPhone SN is as follows: AABCCDDDEEF

AA = Factory and Machine ID
B = Year of Manufacturing (9 is 2009/2019, 0 is 2010/2020, 1 is 2011 and so on)
CC = Production Week (01 is week 1 of B, 11 is week 11 of B and so on)
DDD = Unique Identifier
EE = Color (A4=black)
F = size (S=16GB, T=32GB)

I would like to point out however, that I expect there isn't a supported method of getting the serial number. Assuming you'd only like to know this information so that you can customise your UI, I'd just put in a user option or ask them to select the colour of their device on first startup (or some other early point in the app-user life)
