Apple Watch Complication Template - Modular small image multicolor

Question

Hello,

I'm trying to create a complication for Apple Watch, in the modularSmall family, using a CLKComplicationTemplateModularSmallSimpleImage. I want the image to be displayed as a multicolor image when the tint is set to "multicolor" (just like the calculator's complication). My issue is that it is always displayed as a white image, and never as a multicolor image. I tried to set the tintColor of both the image provider and the template to .none and other various values, but I can't get my full color image when scrolling trough the templates... My code is as follow :

case .modularSmall:
            let imageProvider = CLKImageProvider(onePieceImage: UIImage(named: "Complication/Modular")!)
            let template = CLKComplicationTemplateModularSmallSimpleImage(imageProvider: imageProvider)
            handler(template)

Any idea to help ?
