The 20 presidential candidates taking the national stage during the two-night Democratic primary debates are ready for their close-ups — thanks to some ace TV production experts.

The Wednesday and Thursday debates will feature a historically diverse field, posing a unique challenge for the crew tasked with lighting the stage, according to TMZ.

Because the panel includes candidates of white, black, Hispanic and Asian descent, as well as both men and women spanning a decades-wide age range, the behind-the-scenes team will have to carefully balance the lighting for their skin tones, production sources told the outlet.

The company handling the task, the Manhattan-based Lighting Design Group, previously lit the 2016 Republican debates, but that 17-person field featured almost exclusively white men, allowing for more consistent lighting.

The team will have to stay on their toes, balancing nuanced individual spotlights with overall lighting for “broad look” shots — which could bleed into and throw off the candidate-specific lights, sources told TMZ.

Lighting Design Group didn’t immediately return a request for comment from The Post.

The debates, which will feature 10 candidates on each night, will air from 9 p.m. to 11 p.m. local time on NBC, MSNBC and Telemundo, as well as on Twitter and Youtube.
