I am not in disagreement with those stating the blue showing indicate a male. Garret and Action Jackson have more parsons experience than I do. It's hard to get a clear impression, based on the photos and while behavior, feeding, and the appearance of striping are not definitive, they are clues. The shape of your chameleon's face seems male, in the first photo, and I would not be surprised if it were male. When I suggested female, I was making a guess based on my perceived size of the animal. Assuming, as I did, it was the size of my current animals, if it still looked as yours does, I'd be very suspicious of it being a female. If your parsons is smaller and therefore younger than I was able to estimate by the photos, then you are likely going to have a male.
