Royal has one that looks dark blue to me. I saw it in a book at a local lumberyard. The brand was royal but that was all I remember about it. I don't remember if it was vinyl or aluminum siding or what.

Are you specifically looking for a siding that is already colored? The kind we used on mine was painted any color we wanted.

Jloglow....beautiful color!!

Thanks Michelle! It's Glidden's Cool Metalwork Grey. It's funny initially I was going for something way more gray than it turned out but now I love the color. It's like a smoky blue gray.

Vinyl is generally not done in dark dark colors due to heat buildup and potential damage to the siding from it.

Dark colors will fade, a lot.

It was true that vinyl wasn't done in dark colours 10-20 years ago. It's a different product now. If you're interested in vinyl, Royal's wedgewood blue is a very dark blue. My neighbour has it, and I snooped on the boxes when it was being installed.

True but there is also reasons many companies still do not offer it and the color selection is very limited.
