It was custom. The color is a charcoal grey with some blue in it.
Even if I knew the actual color chip it would look different in your application due to
1. Your computer / device screen sees color different from real paint
2. The photo changes the color from the actual paint
3. Your application will look different from the color selected based on the light in the room. We have used the same color in two different houses with different lighting / sun orientation and they look completely different. I thought they'd used the wrong color!
I recommend getting some samples and seeing what looks good in your room.
The paint chip fans the paint companies use are not paint, they are a photo so it is best to get sample pots of paint and hold them in the orientation of the cabinet.
