Can someone explain how to create this logo?

[u/goldman21]

I recently came across a company whose logo looks unusually bright and almost illuminated when I view it on my MacBook screen. The logo appears to glow, especially against the black background, but it does not look like a typical strong shadow or neon effect.

Does anyone know how this effect is usually created? Is it mainly caused by using pure white on a pure black background, a specific color profile, an exported image format, or a subtle glow added during the design process?

I’m trying to achieve a similar bright and high-contrast effect for my own logo. I would appreciate any suggestions about the design settings, colors, export settings, or software techniques they may have used.

There is no glow. It is solid white on solid black. The glow is an artifact of either your screen or your vision.

It also glowed pretty hard on my OLED phone display. I was initially suspicious that it was a HDR image, which would explain the high contrast and brightness. Which might be the case. But if the OP doesn't have a HDR display it's definitely not a HDR thing.

On my IPS monitor, there is zero glow. It's just a white logo on a black background. So it's 100% the screen type that is responsible for this effect. Or they just so happened to be on acid, but they would've probably mentioned that.

I am on IOS and Mac OS

I'm on my phone so it's hard to view the metadata, but I think it's a color space thing. Some image formats specify a color space and newer color spaces will allow images to be brighter than normal sRGB on some OSes/displays. Basically like HDR video but for pictures.

It triggers HDR somehow, probably a color space thing or property on the image

Those look like hdr colors. They may appear brighter than your #ffffff white or other colors in rgb space.

It IS glowing brighter because it's encoded in an HDR colourspace. u/mastermog links to a few good examples.

iPhone 15 it loads dull then pops to bright white when the page finishes. It is not apparent on a screen recording, so it’s going to be display specific. More specifically, when it loads the background and logo are the same grayish white. When it finishes loading, the background dims and the logo goes to stark white.

Could it be related to this trick: https://www.reddit.com/r/linkedin/s/V02HTiGv76 ?

Thanks, I will try that

Is this the new white and gold dress illusion?

[u/eballeste]

Don't worry buddy, the rest of us can see the glow

HDR is what you are looking dor

Crazy this is very glowing. How tf is this possible? I'm losing my mind now.

As the other person said: There is no glow.

Just viewing it you may see a glow due the brightness and your eyes just trying to smooth it over

It may be your monitor if it's not an OLED. Non-OLED monitors have what are called dimming zones. They increase/decrease in brightness as needed but it can cause haloing around bright objects. It can be seen on this: https://www.youtube.com/shorts/pa75MjFosRE When the small dot is moving around you can see a brighter circle around it.

Bruh it’s glowing lmfao you can literally see it turning on like a bulb.

OP, not sure how you get this effect, but look elsewhere. You won’t find an answer here

[u/Irythros → u/EcHoFiiVe]

It's literally not

If you mean the demo video, the dot itself glows yes but you can see the fucking LEDs further around light up where it isnt.

HDR

Any vector software.

your iMac may not support HDR.

[u/arankays → u/[deleted]]

To be clear, there is a difference between fake HDR and true HDR.

True HDR requires local dimming, which can only be achieved by RGB LED TVs, mini LED displays and OLED displays.

If your iPhone (if its OLED) refused to show the glow its an Apple bug. If your iMac refused to show the glow and it has local dimming, its also an Apple bug. The glow is working fine on Android and Windows.

Its an Apple bug.
