Bug in selecting color

I have an original Hue bridge but with non original Philips hue lights i can set colors but a few seconds later the app shows a different color.

Yesterday i installed diyhue for home assistant, added my own esp8266 light and the same happens, even if i turn off the esp8266, the hue app changes the color after a few seconds, even multiple times. Is this a bug or how can i solve this?

no guarantee but ive found there can be funny behaviours if the wrong bulb type is selected. Long shot but worth looking at

Thank you, is it just try and catch or is there a way to figure out what type i need to select? And i am programming my own firmware. What would the type do?

I disabled all the communication as a test and it still does this
