Color Calibration issues?

[FelixA02]

Hey Awawa-dev,

I'm having trouble getting the correct color output for my setup. Despite checking the live video feed, LED visualization, and my screen, everything appears to match, but the actual color displayed in IRL by the LEDs is incorrect. I was hoping you might have some insights or suggestions.

Here’s a breakdown of my hardware and software:

LEDs: SK6812 Cool White 6000K  
LED Controller: Adalight Feather Scorpio  
Software on LED Controller: HyperSerialPico_sk6812Cold.uf2  
Main Hardware: HyperHDR running on a rooted LG C3 42-inch TV (using Satdx62’s modified version, currently at v22.0.0beta0)  
Capture Device: PicCap (I don’t think this is the issue since the live video feed matches what I see on my screen)

I’m using my own calibrated Compressed LUT for SDR, HDR, and DV configurations. For this example, I’m testing with SDR content.

I’ve tried resetting all settings to default, thinking I might have accidentally changed something important, but that didn’t resolve the issue. At this point, my only theories are:

 My color perception is being influenced by my blue wall.  
 I might be experiencing some form of color blindness, which would be surprising as I’ve done basic tests that haven’t revealed any striking issues.

Do you have any ideas or suggestions to help me troubleshoot this? Any guidance would be greatly appreciated!

Best regards

Did you test using static colors in the remote tab? Especially red, green, blue?

just tried using the colors/Effects in the Remote Control settings. red green and blue work there not the most accurate since on my screen they look a bit darker compared to what i see IRL but i would say that they are close enough. but anything that combine with R.G.0 is off, i cant get any yellow or orange, id say they are more green than anything. and for pink and purple i do see it but they are way less accurate than expected. id say pink is more like the purple color and purple is a mix of blue and purple

The requested colors in the remote tabs bypass the LUT and are rendered directly, so you will need to diagnose yourself what is wrong with your setup. Maybe you encountered some faulty LEDs or have a different RGB order than standard, although that can be changed. I can't read anything else from this story that could help.

Alright, thank you very much for taking the time, it gave me a few ideas I could try out now so that I can more easily reduce the scop that I need to look at to find the issues. Will post again if I ever find it

First try to reorder RGB in your LED driver. Or use the RGB wizard in the advanced settings (misc) to see if there is any difference.

Tried all the different options for RGB byte order and I found the one selected by default(RGB) was the only one that had the Red Green Blue correctly identified. After trying to add some White to my Wall I did find that it fixed most of the issues. After that I manually reduced the max White output of the controller to about the same as on the tv which is at 60 since I find that oled at 100% is way to bright for me 😅. I think i got it about 90% accurate per color (meaning it's about 90% the color it should be) for the whole Spectrum. Now I'll do more testing since after trying to see it on some content I do find that all of the color seems washed out like they were fading.

I will try to continue working on that tomorrow.

Also on another topic should I be adding defusers on the leds. What are the benefit and disavantage of doing it.
