The spectrum was a range of light, which included the visible spectrum, and the ultraviolet and infrared light spectrums. Different species could perceive different spectrums; the Keshian were able to see a spectrum that included ultraviolet and infrared, while the Chiss had a visible spectrum that edged slightly into the infrared. The Pantoran Jedi Padawan Kevmo Zink believed that Rodians and Pantorans saw a different light spectrum. The star of the Unknown Regions' Sunrise system had a spectrum compatible with standard life-form paramters.
