Regarding Brown color film. Our R&D is working but it’s hard to get the your target.
Option proposal.
1. Color can make same as sample. but IR can work only 30%
2. IR can make upto 80% but color will change dark yellow.
Technically brown color is very hard to make IR film,
I will wait your instruction for further R&D works.
