The first thing I do is create color grade and palette and lighting consistent for every character. These are our heroes, spies set in a fictional world of the Cold War of the late 60s. They are the CIA, CID (China), KGB and MI6. The story begins with two nuclear silos mysteriously blowing up and wreaking havoc. One in the USA the other in the Soviet Union. Next Ireland has completely disappeared, then Japan... and we haven't even touched upon a slew of worldwide assassinations...
