True positives or false positives?

I’ve gotten 3 positive blue dye tests, but negative on the pink dye. All 3 pictures took within the time frame. The line is getting darker each time. The top 2 showed up within 1 minute, and the most recent one I took showed up IMMEDIATELY. But I just took a pink dye and it was negative😞 please help me... am I crazy? Are all of these tests false positives?
