Hello,
I got two different answers (input color to FFF or output color to FFF)
so I tried both but the white overlap is still there...
Any idea ? If someone is interested in testing himself, the
Luxembourgish JP2 file are freely available from the link of my original
post.
Thanks in advance,
Adam.

Dear Adam,
setting the input Transparent Color to FFFFFF "should do the trick,
however JP2 is a strange best and there might pixels that "appear"
white but they are not.
I will have a look.

Hello,
I have imported all JP2 from the link below (except _1.jp2, _10.jp2,
_100.jp2 which are lightweight variants) into an ImageMosaic store.
https://data.public.lu/fr/datasets/orthophoto-officelle-du-grand-duche-de-luxembourg-edition-2016
However, it's not working correctly, see the attached screenshot from
layer preview. Also, when querying WMS, I receive a valid image for a
given bbox not being into the white part in preview, but if it is, all I
get is blank.
I think some pictures overlap others without applying proper
transparency, so I tried to set Input Transparent Color to FFFFFF but
then everything is blank.
I'm not sure what's going on here so I checked the JP2 files using
gdalinfo (homemade build, include jasper, ECW, MrSID) and I cannot see a
"mask" inside metadatas so I guess I can't use "Footprint behavior"
option in layer config, but I'm not sure.
Any help would be appreciated, I'm stuck.
Thanks, Adam.
