Camera shows extreme red hue

Hello Everyone,
I have a problem with my Framework camera: Under artificial light my skin looks like I spent too much time at the beach and am experiencing a bad burn! Framework sent me a new camera, but that has not solved the problem.

Is anyone else experiencing this, or does anyone have an idea what might be wrong? Thank you!

Can you post a photo of the issue? A printed color-checking sheet should give the gist. I was thinking that a connector might be improperly seated, but most devices use USB. Rarely, although possible, there might be a red film on the camera, which is required for PnP assembly (pick and place). Try peeling the bezel back and taking a picture.

Hi StarEngineer - Thanks for responding!

I actually had Framework send me a new camera, replaced the old one, and while there is some improvement in natural light settings (looks normal most of the time), as soon as I turn on the inside lights I look beet red.

And I’m bald so this is no help.

I can’t attach a photo (something about new users not being able to). Thanks for your help!

I think Imgur links would work, just have to click to see the image.
This might be due to the wavelength of the light, as very specific wavelengths might register as red on the camera. This is an example spectral response curve for a Canon 40D camera, the FW can have a different one.

I’m having a similar issue. I adjusted the saturation on the camera settings in linux using a python tool called camset. It’s better, but still not perfect. The camera just seems to oversaturate red.

It’s the lack of decent auto white-balance.

Also, there’s no mention of the colour reproduction accuracy…it’s not just the web cam. You need to consider the display as well.

What your eyes perceived is a compounded output from the webcam AND the display panel, in conjunction with your ambient lighting conditions.

So technically, " Camera shows extreme red hue" (when talking about the Framework laptop webcam) is incorrect, as web cam (and other sensors) are not for displaying / reproducing colours; The web cam does not “show” things…it interpret photons wavelengths and encode that digitally to represent the colours that it perceived.

In short, there are at least two things to calibrate; The display panel, and the web cam white balance algorithm to match its environment.

I understand your logic but beg to differ: Others who are observing me via video see that I look like a big ripe tomato, so there you have.

I feel very sad about this laptop. SUCH promise, SO MANY issues. I really really hope they are just growing pains. My trackpad does not allow me to pick things up anymore. I will fiddle with the settings but I’m not confident, given the hardware problems I’ve had since Day 1.

Anyone else with a DIY Framework having nagging issues? Is it just me? Should I give them another shot or bail when it comes time to buy new?
Thanks everyone!

That’s new information. So given this, yes. It’s likely the camera has a lack of [decent] white-balancing.

I want to comment on this…but will likely perceived as the ‘dark cloud’.

@David_Herst - what OS and video application are you running?

I’d say if you can’t confirm that the system will work the way that you need it to, hoping that one day it might isn’t necessarily a great bet.

Ah…found this, tested it out, seems to work. You need Skype installed…then you can adjust the camera settings.

In my case, I turned the saturation down from 60, to around 36-38.

This is important information. It is hard to help without this info. If you are on Windows, and you’ve installed the Framework driver bundle, then this sounds like you will need to contact support.

Other wise, it could be a misconfiguration if on a Linux distro not widely tested by Framework and the community here.

I think you should give Framework the opportunity to help you out. Please understand that this is the first thread on this forum about this issue. (that I’ve seen) It doesn’t seem to be a common problem.

Despite my myriad of hardware problems with the laptop, Framework the company has been STELLAR. That has kept me around.

As for the red camera hue, they quickly sent me a replacement camera and the problem has persisted. The problem shows up on any and all video applications I use, including WebEx, Zoom, and Screen cast-o-matic. It forces me to use an external device.

I am running Windows 10 with all updates.

Thank you for your input!

Grab Skype from the Windows Store, then from that, configure the camera settings. The setting is applied to the camera [logical] device, not the app, so it will carry through to your other cam apps.

Or if you want to go the really DIY route:

I hardly ever use the camera but I was curious. And yes, it seems that the camera’s default saturation also gives my skin tone a spent-a-little-too-long-in-the-sun look.

On Linux/Fedora:

$ sudo dnf install v4l-utils
$ v4l2-ctl -l

looks much better.

Haven’t looked into making this “sticky”, doesn’t bother me enough to go write a systemd unit for it.

Very nice @dimitris, thanks!

I hadn’t considered that the issue was simply software / driver tuning. Very cool to see.


I have the same issue on Linux (Ubuntu 22.04).

I installed guvcview and tuned the camera profile.

It’s not that perfect. Now I’m a bit too much desaturated but at least my face is not red anymore and the colors of my clothing look normal.

I am using v4l2-ctl as well. It seems odd that I have to do this, though. I have not had to do anything with other laptops and… Well, those of us with Scottish heritage will never like the color that a camera gives us, but it seems odd that framework’s camera is noticeably worse than others.

The v4l2-ctl -c saturation=30 solution works for mee too and is persistent after a reboot on Pop!_OS 22.04. Thanks, @dimitris

Big thanks to A_Fan for the Skype saturation fix solution to this problem. I have suffered long enough as a big red tomato, now I look relatively normal!

I used @dimitris suggestion. I’m able to bump it to 45 to get a slightly more natural feel without the redness.
