Black Grey Professional PowerPoint Background with Wide Slate Diagonal Bands

Free black grey professional PowerPoint background with wide slate diagonal bands and soft light. HD 16:9.

Created by Elena Gidura · November 12, 2026

This black grey professional PowerPoint background lays wide, blurred diagonal bands of cool slate across a near-black field, brightest through the middle and darkest at the top corners. A thin pale streak edges the lower right. I kept it smooth, with no shapes. Put your title and text in white on the dark upper left. Fits boardroom and finance decks.
