Hi,
Sorry for double post, but two topics with same problem.
I installed Firmeware 1.4.2_0044 and rechecked the colors. Red was fine before, you fixed blue, but green is still wrong.
If I just turn green, red is still on too, that should obviously not the case.
Red 255,0,0
Green 0,255,0
Blue 0,0,255
After the update, blue looks totally blue however if i slide the slider slightly to aqua blue / turquoise the light suddenly appeared blueish white (no gradation between blue and green) and the pure white still appeared warm white.

Colors do seem odd now
If I do brightness @ 100 then:
Blue 255
Green 0
Red any value in 0 - 121 range
Red doesn’t turn up at all
Then Red @ 122 is first value when red led lights up, this does cause sudden jump to pinkish/purple

Can you comment on the following results publishe on another very respected forum:

All 3 of my light strips were working fine for months, and then I couldn’t get blue on one of them. The firmware update did fix this.
But now on all my light strips, I cannot get all the colors I used to. For example, I used to have them set to a deep blueish-purple, but now if I move the slider to the same location, it just gives me a standard blue. And this is the case for other colors too. Like another member posted above, there are no longer the same gradients between colors.
What’s going on with these things? Could this be another firmware issue? I do have the latest firmware installed.
TIA for any help!
Still problem with bad calibration color!
Still no fix! Very bad
Yes, very bad, colors are wrong!

Are someone working to fix it?
I think that nobody at Yeelight cares about this problem. They made some small changes. The colors are slightly better but far from perfect. I would assume that they are not going to make any more ajustments to firmware. They already got the money for the half-baked product and that’s it!

Still the same problem, one year later, that is more you can expect!
Hi, which firmware do you use now? And which server do you select?
Really? That is your question? Did you ever unpack a lightstripe, put it in a socket, installed the newest firmware and checked red, green and blue?
Pro Tip, use the yeelight app, go to color flow, red, green and blue are default, just take a closer look at the lights and you will see it.
If not, here the explanation: If red comes only red should be on, if blue comes only blue should be on and you can guess it, if green comes only green should be one. The problem is, when green comes red is still on.
The simplest quality assurance test for a color light I can imagine, just give it a try! You didn’t have done it once after a new firmware, I guess.
Customers are not your beta tester! A lot of people complaint about the color problem since one year and you ask which firmware… good joke… every new firmware since and also before October 2017, just choose one by yourself.
That you can not say you can not help me: My current firmware is 1.4.2_0044 and I use Mainland China.
Hey, please calm down, we are working on fix once we receive feedback from Yeelight forum.
Of cause I tried from our lab, it looks well with latest firmware version 1.4.2_0049, but for some reason it is still in QA, it will be approved to release once xiaomi QA team done the verification. So I need to check which version do you use, and it’s need more time to release to overseas servers and I need to know the server you select.
I just check the state of version 1.4.2_0049, it is still in verification, will release very soon. So if you want try it now, please leave you xiaomi account, I will add you in whitelist.
Thanks for understand.
