“Normal” LED with ZWB2 filter

u/Thunderbolt294 mentioned wondering what a normal LED would look like with a ZWB2 filter in front of it. So I took the filter off of my S12 and put it on front of my D4k, which has dedomed 5700K 519a emitters. The pictures look more pink, but the red is a deep red in person. Are we seeing the opposite end of the spectrum here? I know the filter is supposed to block all visible light right?
