What Color Is Glidden Onyx Black, Really?
Glidden Onyx Black reads as a neutral with no strong undertone — very dark — reads black in most rooms. The notes below cover how PPG / Glidden GLN-1 behaves in different light and the closest matches at competing US brands.
Best Rooms and Uses for Glidden Onyx Black
Glidden Onyx Black earns its keep as a statement: accent walls, a front door, cabinetry, a moody powder room, or exterior trim where you want sharp contrast. Near-blacks like this are best as contrast — doors, trim, cabinets, window frames.
How Lighting Changes Glidden Onyx Black
At LRV 3, Glidden Onyx Black is about as dark as paint gets — it reads near-black on a wall and reveals its character only in direct daylight or under warm bulbs. Because it carries almost no measurable hue, it stays a true neutral and pairs cleanly with nearly any trim or floor. In rooms with little natural light it can feel heavy, so reserve it for spaces you want to feel enveloping.
Most complaints about Glidden Onyx Black are a light mismatch. Upload a photo of your actual room and see it on your walls — then ask for the same wall in north light or evening lamps before you buy a single sample.
