Hi, I am looking to get some LEDs with adjustable white color temperature and am wondering if WLED will support something like [https://www.aliexpress.com/item/32634891197.html](https://www.aliexpress.com/item/32634891197.html)

Thanks for your help!

Hi!

This is not currently supported sadly, but is on the list of feautures to add 🙂  
Once there is good color temperature support, PWM WW+CW strips will work well!

Thanks for the quick response! Is there a GitHub issue or thread where I can follow the work on color temperature support?

Hi @soberstadt,

yes you can look here: [To-Do-List Aircoookie](https://github.com/Aircoookie/WLED/projects/1) or here: [To-Do-List Def3nder](https://github.com/Def3nder/WLED/projects/1)

Hi, may I suggest using HSI colour coordinate system? It’s very scalable in this regard

- for RGB it’s straight-forward, hue is colour wheel angle, saturation adds remaining colour channel(s) and intensity dims all equally
- for RGBW saturation fades between saturated colour and the white channel
- for RGB-WW-CW a temperature value is added and it controls the WW-CW mix, the mix is then used instead of white channel for saturation control
- and for WW-CW only, hue and saturation get dropped, temperature and intensity remain

[this article explains it better than me, sans the WW-CW](https://blog.saikoled.com/post/44677718712/how-to-convert-from-hsi-to-rgb-white)
