This is likely because you are using your AppIcon image, which is a fully opaque image, i.e. no part of that image is transparent or has alpha=0.

To get the desired effect, you have to use a different image which is partly (or mostly) transparent. The native in-call UI will only use the alpha channel of the image you provide, so it ignores colors. I suggest following the example in the Speakerbox sample app and providing a secondary PNG image in your image asset catalog with transparency.
