What do these new colors mean?

[Thompson]

Ariel has had these colors for the past two days and she usually displays a nice light brown tanish color with a few spots of blue on her. Now she's pink and black with a few spots of purple. She certainly doesn't look gravid to me and these aren't receptive colors since she hisses at my male when she sees him. So what do these colors mean? I also don't think she's stressed. She acts normal and the same as she always does, nothing out of the ordinary.

and here is how she usually looks

My female changes colors similar to yours. She usually will display those darker ones like in the first photo in the morning and she lightens up. Probably trying to absorb some heat.

Yes that's true. But I also thought colors like these mean gravid? Half the time she wasn't basking and still had these colors.
