Confused as to why its gray? Faulty test or normal?

Im not trying to be prego. In fact, dh and I just separated 2 days ago. But I'm late and bc im psycho, I took a test this evening. (I know I know, test in the morning) (and I also know I shoukdve gotten a first response. But, dang, their expensive ok lol)

Was happy to see it neg. But with the neg result so faint and GRAY I'm wondering if it was faulty? What are your thoughts.
