Same here; just paired my Tradfri color bulb with Hue bridge, and it’s recognized as “0200”. So I perfectly can dim, but it’s not possible to set bulb color by (H,S,B); Hue App seems to work as intended. Did you raise a GitHub issue I could subscribe to, @Hendrik_Nielsen?
Cheers,
Marianne
The Problem is, the IKEA RGB Bulb accept no CIE Color Mode… only XY Color Mode … 
And the HUE Binding use CIE Color Mode
I have the same problem, but if it works in Hue App it should be possible to get it to work in Hue binding.
/Mike
No … the Code of Hue App and the Code of Binding is different … the Maintainer or any one other … must create some code for the Binding … or adopt it from the Tradfri Binding… without Code changes it will not work.
That was what i meant.
I understand that we have to change the code in the binding, but it should not be an technical issue that stops the possibility to get it to work.
/Mike
Okay 
Please note my comment in the other thread. If nobody does that you’ll never see a result. Thanks.
I add a Issue here… feel free to comment this Issue … and explain your Problems
Kay answered that the hue bridge should handle the conversion. But why is the binding not just sending everything as XY for max compatibility? Is there any downsite?
Is the problem not caused by the recognition of the bulb. If I remember well my bulb was recognised as type 200 and not 210. I think the recognition is done by the binding and something is working not correctly there…

Thank you very much … Works great.
Hello, i have one question 
Where do I have to put the BashScript?
Or what do I have to do with it?
Here you see the place of the Script 
Hello, I made the whole afternoon and did not manage it.
Inside my item:
Switch Schl_Bambus_bu "Schlafzimmer Bambus" <light> (gSchl,gLicht,gLicht0,gLicht2) ["Lighting"] {channel="hue:0200:00178821c409:6:color"}
Color Schl_Bambus_bu_Color "Schlafzimmer Bambus Farbe" (gSchl,gLicht,gColor_schl) ["Lighting"] {channel="hue:0200:00178821c409:6:color"}
Dimmer Schl_Bambus_bu_brightness "Schlafzimmer Bambus Helligkeit" <qualityofservice> (gSchl,gLicht,gBrightnes_schl,gBrightnes_all) ["Lighting"] {channel="hue:0200:00178821c409:6:color"}
Switch Schl_Bambus_bu_Effect "Schlafzimmer Bambus Color Loop" (gSchl,gLicht) ["Lighting"] {channel="hue:0200:00178821c409:6:effect"}
String Schl_Bambus_bu_Alert "Schlafzimmer Bambus Alert" (gSchl,gLicht) {channel="hue:0200:00178821c409:6:alert"}
Then i created a file called hue_tradfri_color.sh
/etc/openhab2/scripts/hue_tradfri_color.sh
hue Brige user i have a little bit alienated, but the rest is original

Unfortunately it does not work yet. If I enter the content from the bash individually, he already changes the colors.
What do you mean with this? --> 3 Stehlampe_Wohnzimmer_Schrank_Brightness " + colorpicker_wohnzimmer_schrank.state)
Sorry for my bad englisch ;-( And thank you for your support
I’m not sure, why you have modified the bash script. But don’t replace the params $1, $2 and $3 with a static content. Otherwise you could use the script only once for one bulb and executing with 3 Schl_Bambus_bu_brightness"+ Schl_Bambus_bu_Color.state doesn’t make any sense
According to your example, I have the following suggestions:
items file should look like this … it makes actually no sense to implement the other channels for a colored tradfri bulb at the moment, because they don’t work (as expected).
Number Schl_Bambus_bu_brightness "Helligkeit [%.0f %%]" <bulb>
Number Schl_Bambus_bu_colorpicker "Farbwahl"
Color Schl_Bambus_bu_color "Farbwahl" { channel="hue:0200:00178821c409:6:color" }
rules files should look like this
// RGB Workaround Schlafzimmer Kugel
rule "RGB Workaround Schlafzimmer Kugel"
when
Item Schl_Bambus_bu_colorpicker changed
then
executeCommandLine("/etc/openhab2/scripts/hue_tradfri_color.sh 6 Schl_Bambus_bu_brightness " + Schl_Bambus_bu_colorpicker.state)
end
Where <6> is the number of your bulb (e.g. from hue:0200:00178821c409:6:color)
So use the script hue_tradfri_color.sh as provided by @ei_Gelb_Geek.
The only things, that have to be changed are:
openhab_ip -> set it to your openhab ip
hue_bridge_ip -> set it to your hue bridge ip
hue_bridge_user -> the user hash / secret, you’ll have already
#!/bin/bash

bash /etc/openhab2/scripts/hue_tradfri_color.sh 6 Schl_Bambus_bu_brightness " + Schl_Bambus_bu_colorpicker.state
for debugging use
bash -x /etc/openhab2/scripts/hue_tradfri_color.sh 6 Schl_Bambus_bu_brightness " + Schl_Bambus_bu_colorpicker.state
In the script $1 is replaced with the bulb id (6), $2 is replaced with the (dummy) brightness item, $3 with the number from the dummy colorpicker (0 - 12).
The script will do a http request to the hue bridge
curl -s -H "Accept: application/json" -X PUT --data '{"on": true,"xy": [0.5234,0.4023]}' http://$hue_brigde_ip/api/$hue_bridge_user/lights/$1/state
like
curl -s -H "Accept: application/json" -X PUT --data '{"on": true,"xy": [0.5234,0.4023]}' http://192.168.1.11/api/zaishiyahl8eemee1aengud7zeikihe6aeDu/lights/6/state
and the color of the bulb will change.
Afterwards a rest call is done to the openhab api to update the dummy brightness item from the item definition. This has nothing to do with the “real” brightness state of the bulb. If you change the brightness of the bulb through the app, the item will not be updated.
I’m not sure, why @ei_Gelb_Geek has done this, maybee he wants a feedback in the sitemap and / or can tell more about that feature.
From
curl -X POST --header "Content-Type: text/plain" --header "Accept: application/json" -d "50" "http://$openhab_ip:8080/rest/items/$2"
to
curl -X POST --header "Content-Type: text/plain" --header "Accept: application/json" -d "50" "http://192.168.1.10:8080/rest/items/Schl_Bambus_bu_brightness"
Sitemap code should look something like this
Frame label="Ambiente" {
Switch item=Schl_Bambus_bu_color label="Farbkugel" icon=crystalball
Text item=Schl_Bambus_bu_brightness
Selection item=Schl_Bambus_bu_colorpicker label="Farbe:" mappings=[
0=" Warmes Licht ",
1=" Tageslicht ",
2=" Nachtlicht ",
3=" Sonnenuntergang ",
4=" Gelb ",
5=" Helles Gelb ",
6=" Helles Grün ",
7=" Orange ",
8=" Helles Orange ",
9=" Rot ",
10=" Pink ",
11=" Helles Lila ",
12=" Blau "
]
}
The real color item of the bulb (Schl_Bambus_bu_color) is mapped to a switch, because ON/OFF is actually the only command that works like expected.
Hope this helps to understand the workaround solution.!
The sitemap looks like that …
Hello Jens. Thanks alot. unfortunately it does not work yet. I do not know why. In fact, I have adopted and aligned everything, such as the hue_bridge_user and ip addresses. The api debug tool (hue) is the color change correct 
Try this Commands in your Shell …
bash /etc/openhab2/scripts/hue_tradfri_color.sh 6 Schl_Bambus_bu_brightness 1
or
bash -x /etc/openhab2/scripts/hue_tradfri_color.sh 6 Schl_Bambus_bu_brightness 1
if this not work, post a Screenshot from the Response …
