Making some layers immune to blending modes

[Reindeer]

I have a scene to which I superimposed a black layer and then chose 'color' as a blending mode. The result, as desired, is that the whole scene is turned into a black and white one.
I would like to keep a couple of layers immune to this colorisation mode, but I can't achieve this by simply dragging them on top of the black layer because they need to be where they are in the layer order.
So, just wondering if there's a way of excluding them from the effect (i.e., without having to export them separately and do the comp in an editing app).

In Moho, you'd have to do something like use a reference of each layer as the blend layer for each one individually. Probably better to comp it.
