greenness

The state or quality of being green; green colour.

Her crimson dress inflames grey corridors, or flaring in a sunshaft through high branches makes of the deep green shadows a greenness darker yet, and a darkness greener.

Vitality, freshness.

Inexperience.

The chances were that, sooner or later, such greenness would inevitably lead to a graver disaster.

The fact of being environmentally or ecologically conscious; commitment to environmental conservation.
