Show HN: Make your logo extra bright on HDR screens

I’ve always wondered why it happened, assumed it was a rendering bug.

fwiw it seems like “reduce white point” overrides any of these effects - which is good.

> Every social network strips these tags except the worst one

> Clearly we need more of it

I do not in fact want sites trying to get around my display preferences to post their visual presence on screen.

For your uBO (Lite) custom filters

Please don't

I hit an advertisement in Gas Buddy that was super bright, clearly using HDR yesterday. Bummer.

I’ve noticed this trend on LinkedIn just recently. Very noticeable at night, obviously, when my screen is naturally more dim. But these logos are like blinding headlights.

For an authoritative overview of high dynamic range on monitors, I recommend the 137 minute documentary Debunking HDR (Steve Yedlin, 2025) https://news.ycombinator.com/item?id=44248968

Look at the bright side, if it starts to get really overused then maybe the other platforms like LinkedIn will start stripping them too.

I'm on an SDR setup so I wasn't expecting to see the proper effect, but the square labeled "SDR White" is actually `rgb(220, 220, 220)`.

Oooh fuuuuuuck. Do we now have the HDR screen version of the 90s/00s CD volume wars? MAX IT OUT?!? BE LOUDER! BE BRIGHTER! WTF.

In Firefox, the page tells me neither my browser nor my display support HDR. In Chrome, it works fine. Latest browsers on a Pixel 8.

If you use HDR videos, you can get bright white even on soon browsers that don’t support HDR images

I just noticed something similar today as an ad where the green oval button was so bright that the rest of the white screen felt grayish/dull than white. It could not be unnoticed playing on the notion that the eye is attracted to the brightest thing on the screen

This extra-bright-everything-on-HDR-screens crap makes me navigate away from sites every time.

Immediate irritation and if I could setup an adblock rule to stop it somehow, I would.

The worst cases give me the starting pangs of a headache, and make me adjust my display to account for it.

Can we somehow make it a rule that a website has to ask if they can blind me first?

I hate gain maps in JPEGs. I noticed that because I insisted on capturing JPEGs and not HEIF on my iPhone, and I found that the iPhone would also show overexposed parts (such as the sky) brighter than plain white. That's how I came to know gain maps. Fortunately on iOS, although I cannot disable the inclusion of gain maps in photos I take with Camera.app, I can stop Photos.app from rendering them: just turn off "View Full HDR" in the settings.

The Metapho app on iOS seems to be a good app to view the gain map itself. I give it no access to my photos and use the share sheet to view gain maps of specific images.

Waddabout an ImageMagick command or explanation how to export in Inkscape?

Please don’t do this.

You know it will be annoying.

This is fun and will try to embed it in our project next week.

Now someone vibe-code a browser extension which detects this and removes it.

A uBlock Origin rule for the whole domain of anybody who does this would be fine too.

This seems like yet another reason to not run HDR. It is kind of annoying even when used responsibly, but now we'll have people using it irresponsibly too.

The page says it should work on my phone but it doesn't. No difference between the SDR and HDR versions on my phone (S26 Ultra / Chrome).

Now how can I draw Vantablack text on HD white for the highest possible contrast?

It seems you have seen the same logo in LinkedIn that I did :)

Works for text too!
