A troop of opalescent shades.

The Terrace, and the gardens that dropped below it to the Thames, were bathed in the purplish opalescent shades of evening.

Brilliant light flickering through opalescent shades rose up in front of me, as bright as the full moon and as solid as ice.

For large reception-rooms in hotels and public institutions the plan is frequently adopted of having all light provided by small table lamps with opalescent shades.
