The lighting in the opening sequence of the Netsu Ijou 3DMV is designed to mimic the opening of the original MV. The original MV starts out very dark, with only the character's eyes and hair being a bright red, though it gradually fades to being in full color and brightness. In the 3DMV, a similar effect is created with the red lighting, being much harsher and only lighting up parts of Kanade and Mafuyu's hair and eyes at the start, and becoming brighter towards Ena and Mizuki's parts, allowing us to see them much more clearly.
