Most of the ancient buildings at Chichen Itza are devoid of color; only the limestone is exposed. But during the Mayan occupation, archeologists believe they were covered with painted plasterwork. This is how Casa Colorada (Spanish for Red House) got its name because traces of red were found on the façade. Alternatively, it is called Chichanchob meaning Little Holes, a reference to the perforated roof. Debate continues whether this Puuc style structure was built in the mid-9th century (Terminal Classic period) or around 600 AD during the Late Classic period.
