Grim...I understand your question (I think) and I suspect what you are really after is the best colour filter to use..but like I say above .....
They can see light intensity but not orange colour...so they can't see orange, but they can see your light so orange filters are a waste of time!!!
You might just as well use an unfiltered lamp with a dimmer control on it as I do if that is the case
I hope someone can explain this if I have it wrong as it seems that any filter is a waste of time......light intensity is the apparent answer so dimmer units are required not filters....HE
