You should show the Nitrite first really.

I am interested what people say as well - that is the same color I get from my tap and tank. In my journal I am keeping, I just keep putting 0 - 0.25 because it appears to be somewhere in between. I checked mine with bottled water, tap water and tank water and all of my ammonia test is the same as yours. I wish the API test color chart would show what you actually see instead of the vivid colors on the chart. I have never gotten a vivid yellow.
