Why is my decal so greyed out?

I have made a decal showing a coffe cup.
But the decal turns up greyed out!
Something to modify?

I have enabled under Project Settings DBuffer decals, Early Zpasses - Opaque and masked meshes, Movables in early Z-pass.
But it does´t help!
I need some help.
I believe I solved it… by using Dbuffer Translucent Color for the material.
