Uplighters work well, but avoid the grim plaster things, they're just
a mistake.

The quarter sphere things ?
I think they look good in hallways and landings, but nowhere else.
But they look tasteless when painted the same colour as the emulsion !
Simon.

I reckon my grim plaster things look OK, emulsioned the same colour as
the walls. I've got oak beams, pine wainscotting, and exposed stone
above an inglenook to provide visual interest, the uplighters just blend
in. YMMV
