adjective
diaphanous
dy-AF-uh-nus/daɪˈæfənəs/
Light and delicate enough to let light through.
Sunlight filters through the diaphanous curtains beside the kitchen table.

Etymology
The image is of something appearing through a material. Diaphanous fabric lets enough light through for what lies behind it to remain visible, giving the word its sense of delicate near-transparency.
In context
There was a diaphanous, lilac mist on the lake, shrouding the island. Through it the two enormous pine-trees that clasped hands over Barney’s shack loomed out like dark turrets.
