That is her bredding/ agression colors, which she stays in 90% of the time. Here's a pic of her last Feb when she wasn't "dressed up". I don't have a pic of her when stressed but she almost turns a copper color.
Some love pic's when they first met

Congrats! They look very good. Some days I regret selling mine when I see great shots like these. But maybe I'll get another pair some day. I hope they live a long and productive life with you.
