How to Use the Blue Hour Lighting Effect for Video Calls and Presentations

Client calls, investor updates, product demos — the backdrop behind you says as much about your brand as your slides do. A blank wall reads as an afterthought; a cool, cinematic gradient reads as intentional. The Blue Hour lighting effect turns any spare screen into a twilight-toned backdrop in under a minute, giving you a modern, professional visual anchor without buying a single piece of hardware.

What You'll Need

• A second screen or spare monitor to dedicate to the backdrop (a laptop, tablet, or old monitor all work)
• A dimmable room, or at least control over overhead lighting, so the blue tone reads clearly on camera
• A separate light source aimed at your face — Blue Hour's own gradient fades to near-black toward the bottom, so it's built as a backdrop, not a key light
• Your video call app or camera preview open, so you can judge the color live rather than guessing

Step 1: Open Blue Hour and place your screen

Open the Blue Hour effect on the screen you're dedicating to the backdrop, and position it behind you, beside you, or angled to face the camera directly as a colored background panel. The effect renders as a vertical gradient — bright blue at the top fading through deep navy to near-black at the bottom — so where you place it determines how much of that gradient actually lands in frame.

Step 2: Decide on Color Temperature

Leave Color Temperature untouched if you want the true blue-to-navy look — that's the default. If you'd rather soften the effect, Warm White or Tungsten shift only the top of the gradient toward orange, muting the blue without losing the shape of the effect entirely. Daylight and Cool White push the top toward white instead. Either way, the navy and near-black lower portion of the screen stays the same regardless of what you pick.

Step 3: Dial in Brightness for your room

Set Brightness to match your lighting conditions — higher in a room with ambient light still on, lower once you've dimmed things down. This is the effect's opacity control: low values sit close to black, higher values bring out the full blue-to-navy range. Watch your camera preview rather than your screen directly, since displays and cameras render blue differently.

Step 4: Add your fill light separately

Because Blue Hour fades to near-black by design toward the bottom of the gradient, it isn't meant to evenly light your face. Keep your existing key light, window, or a WebLight Key Light screen doing that job, and let Blue Hour work purely as the backdrop behind or beside you.

Step 5: Go fullscreen and lock it in

Select Go Fullscreen so the gradient fills the entire display with no browser interface visible. Controls fade out automatically after five seconds without mouse movement, so nothing distracting shows up on your shared screen or camera. Move your mouse any time to bring the controls back, and press Escape to exit fullscreen when you're done.

Pro Tips

• Add your logo before an important call. Every effect page includes a Logo tab where you can upload a company logo and set its position, size, and opacity — a fast way to turn a mood backdrop into a branded one. Those settings save in your browser on that device.
• Use it as an opener, not a constant. Brightness 70–80 in a dimmed room makes a strong first impression at the start of a recording or presentation, before you cut to slides or a brighter working view.
• If the blue looks washed out, check two things. Either Brightness is too low, or room light is competing with the screen — dim nearby lights before troubleshooting the effect itself.
• Note your settings before a big call. Brightness and Color Temperature both reset to default when the page reloads, so if you land on a combination that looks right on camera, write it down rather than re-discovering it live.

Frequently Asked Questions

Why does the bottom of my screen stay almost black? That's intentional. Blue Hour is a top-to-bottom gradient — bright blue fading through navy to near-black — built to read as a moody backdrop, not a uniform light source.

Can Blue Hour light my face for a call, or do I need something else? It works better as a backdrop or accent than a primary face light, since the lower half fades toward black. Pair it with a window, lamp, or a second WebLight screen running Key Light if you need to be clearly lit.

Does selecting a Color Temperature turn off the blue? It moves the top of the gradient toward white (Daylight, Cool White) or orange (Warm White, Tungsten) rather than blue — the navy and near-black lower bands stay fixed. Leave Color Temperature untouched for the true blue look.

Are my Brightness and Color Temperature settings saved between calls? No. Both reset to their defaults every time the page reloads. There's no account system, so note the values you like if you plan to reuse the setup.

How is Blue Hour different from Golden Hour? They're opposite ends of the same idea. Golden Hour gives a warm, flattering glow suited to lifestyle and portrait content; Blue Hour gives a cool, modern tone suited to tech and business contexts where you want polish without warmth.
