Help needed on Trimming for VR Object

Hi all ^^
I have to make a VR object on a wooden model construction for a client.
This is very interesting and part of challenge ^^
My question here is about making a light tent.
I have found the solution to make one cheap, but which color choose for easy trimming ?
I was thinking about Blue or Green...
If someone has a little experience with this please post yours suggestions. ^^
Thanks in advance.
Best regards.

I think blue is the best color.

But It all depends on the subject. Which color is the most far away from your model. I think in this case it wouldnt matter.

If your model has a high reflective property, I would rather take blue. Green is one of the cleanest channel (due the high luminence) so you can get more detail out of it, but because of the high luminence, it's easier shown on reflective materials. If you try to remove the greenish tint, then the subject turns out more red then normal. Thats why blue is easier to remove in post prodcution, but due the lower luminence its easier to miss out some (dust) particles.

few tips here:

Hi Nupsi ^^
Thanks a lot for this reply and link, exactly what I need ^^
I'll post back when my light tent will be finished, I think I found a smart way to avoid paying 700€ for big object light tent for few money (around 40€)
Thanks again and have a good evening.
Regards.

woops....did´nt say a word But if, I would suggest the same as Zephyr did Maybe I would add the following: Keep the distance from the green/blue as far as possible to avoid the greenish tint and to get the background out of focus what makes it far easyer to remove.

Best regards

LOL
Not really but kind of...
I enjoy the fact that you're here to ask you anotherquestion wich has nothing to do with my first one
I've made a hotspot wich shows an image onover, and like to link it with my google maps spots, and in fact trying to dry a little bit my code, but I must miss something

Code

<!-- The Hotspot himself -->
	<hotspot name="hotspot1"
                         keep="true" 
                         url="img/hotspot.png"

                                                   plugin[maps].pantospot(spot1);
                                                   plugin[maps].activatespot(spot1);"
