Truly awesome! I am curious what part of the light spectrum did they use to take the picture? If it was said in the article then I missed it.

The Gemini Planet Imager operates at "near-infrared" wavelengths (Y - K bands), according to Wikipedia. The telescope is designed to detect light generated by the heat of young planets, so infrared is the best bet, I think.

Y band is 1 μm, K band is 2.2 μm [1]. Almost all current adaptive optics systems work in the infrared.
