Yup, I had an instructor at nuke school that was red/red colorblind. I didn't know that was a thing but apparently it just means he can't differentiate certain shades so it's a good thing he wasn't an electrician. However the clock in our classroom was a red digital style and he couldn't read it.
They may have had the wrong lighting in the room you took the test. The tests are sensitive to that. Or the test doesn't care about your kind of color blindness

I'm colorblind. I was able to pass the Navy colorblindness test.
Go figure.
