Why the Lusha logo glows on LinkedIn

PUBLISHED 2 AUGUST 2026 · BY NIMROD YARKONI

The list keeps growing. Port did it first, Wiz made it famous, Taboola brought it to ad tech, and now Lusha's logo is showing up in the LinkedIn feed looking backlit: on a recent iPhone, Pixel or MacBook the white mark renders visibly brighter than the white page around it. Screenshot it and the screenshot looks completely normal. Nothing is broken. It is the HDR glow trick, and Lusha appears to be the latest B2B brand to run it.

What are you actually looking at?

An ordinary static image carrying an HDR color signal. LinkedIn strips most HDR metadata on upload but keeps color profiles, so the file reaches the feed with its glow armed. On HDR screens the whites render in the display's reserve brightness, above the roughly 200 nits the interface uses for normal white. On SDR screens, and in every screenshot, the same file is just a regular logo. No filter, no animation, no CSS. The full mechanics are in the technical write-up.

Why the trick fits a sales brand almost too well

Lusha sells prospecting and go-to-market intelligence. Its customers are salespeople, SDRs and recruiters, people who spend their entire working day inside LinkedIn. The feed is not just a marketing channel for a brand like this; it is the storefront, the product surface and the audience's habitat all at once.

That makes the glow a very literal demo. Lusha's pitch is helping sellers cut through noise and reach the right person. A logo that physically emits more light than everything else in the feed is that pitch, performed. Every SDR who stopped scrolling and wondered why the logo was burning has just experienced the product category's core promise: attention, captured.

From engineers' curiosity to a B2B playbook

The technique started as a niche discovery, first documented by Tom Nick and passed around Reddit, then adopted brand by brand: developer tools, security, advertising, and now sales tech. Each wave produces the same cycle of "is my screen broken?" comments, a teardown or two, and a few more marketing teams adding it to the playbook. The full lineage and credits are in the Wiz post and the Port post.

The wider the adoption, the shorter the window. Slack has already tone-mapped glowing workspace logos, and platforms clamped the equivalent HDR video trick after it flooded short-form feeds. LinkedIn's image pipeline keeps color profiles today, and that is the whole reason the trick works there. Use it while it is novel; do not build a brand system on it.

What's the catch?

• Not everyone sees it. Viewers on non-HDR office monitors, or phones in battery saver mode, see a regular logo with slightly dimmer whites. High-contrast inputs and moderate brightness give the most graceful fallback.
• Too bright reads as glare. Every wave of this trick produces the same complaints: it hurts, change it back. Around 600 to 1,000 nits a mark clearly out-glows the feed while staying comfortable, which is why Superwhite has a brightness slider instead of a fixed maximum.
• The effect is fragile by design. Screenshots, re-saves, cropping in LinkedIn's composer and messenger compression all strip the profile. Only the original exported file glows.

How do you do it with your own logo?

1. Open superwhite.app and drop in your logo. A white or near-white mark on a colored background works best.
2. Set the peak brightness and the glow threshold so the mark glows and the background stays put. On an HDR screen the live preview shows exactly what your audience will see.
3. Download the HDR JPEG and post it to LinkedIn as a feed image. Do not crop or edit it in the composer, that strips the profile.

Frequently asked questions

Why does the Lusha logo look like it is glowing on LinkedIn?

The image carries an HDR color signal that lets its whites render above normal screen white on HDR displays, using the panel's reserve brightness. It is the same technique seen earlier on the Port, Wiz and Taboola logos. On non-HDR screens the image looks completely normal.

Is it a filter or an animation?

No. The pixels are flat and static. The only unusual thing in the file is the color information instructing HDR displays to treat the whites as HDR content, which is why screenshots look ordinary.

How can I make my own logo glow like that?

Embed an HDR color signal so the whites decode above normal screen white. Superwhite does this in the browser: drop in a logo, set the brightness, download the JPEG and post the file directly to LinkedIn without cropping or editing it in the composer.

Why do I see it on my phone but not on my work monitor?

The glow only renders on HDR-capable displays with HDR on and battery saver off. Most recent phones qualify by default; many office monitors and older laptops do not. On those screens the same file shows as a normal, slightly dim image, nothing broken.

Does the glow survive screenshots or reposts?

No. Screenshots capture the tone-mapped standard result, and re-saving, cropping or forwarding through messaging apps strips the color profile. Only the original exported file glows.

Will LinkedIn patch it?

Probably eventually. Slack has already tone-mapped glowing workspace logos and platforms clamped the equivalent HDR video trick. Treat it as attention arbitrage with a window. When the window closes, the file simply renders as a normal image.
