Not sure what to make of my readings. Especially my nitrite - it's a little darker than the blue on the card but not quite purple either. Same with my ammonia, it's def not green but it's not the same shade of yellow on the card.
From what I can tell, it looks like you have a very small trace of nitrites, it's definitely not any shade of purple, not even the light purple color on the card, it's just a little darker than the color blue on the card, but not by much.
