The spectrum encompassed a variety of light types, including the visible range, as well as the ultraviolet and infrared portions of the light spectrum. Various species possessed the ability to detect different parts of the spectrum; for example, the Keshian were capable of perceiving both ultraviolet and infrared light, whereas the Chiss's vision extended slightly into the infrared region of the visible spectrum. The Pantoran Jedi Padawan named Kevmo Zink held the belief that Rodians and Pantorans perceived a different light spectrum than others. The star belonging to the Unknown Regions' Sunrise system emitted a spectrum suitable for sustaining typical life forms.
