DIY Remote Sensing Bandpass Filter with Mixing CMY Inks, Possible ?

I am researching remote sensing for a long time and found a company offer daylight remote sensing filters. I thought if we mix CMY inks and make a pink colored filter , does it become a bandpass filter also or is there other qualities necessary ?

I think to own lots of filters and making lots of pictures and false color and hope for information is good.

I am trained as archaeologist and if I find cheap solution , it would be awesome for many
