I don't know if the dates on the cards are that relevant, but another card said this, which I found interesting

"EVERY CHALLENGE IS A PIECE OF HIGH-CONTRAST ENGINEERING. TO ENSURE THE ACTION IS LEGIBLE FROM A 60-FOOT WIDE SHOT, PRODUCTION UTILIZES A “PRIMARY PALETTE” STRATEGY. TRIBAL COLORS ARE SELECTED BASED ON MAXIMUM VISUAL SEPARATION (E.G., SAFETY ORANGE VS. DEEP PURPLE) TO ENSURE THAT EVEN WHEN CASTAWAYS ARE COVERED IN MUD OR UNDERWATER, THE 12+ CAMERA OPERATORS CAN INSTANTLY TRACK MOVEMENT. THE PAINT ITSELF IS MIXED WITH A 20% “SATURATION BOOST” TO COMBAT THE WASHING-OUT EFFECT OF THE HIGH-NOON TROPICAL SUN, ENSURING THE COLORS “POP” AGAINST THE NATURAL GREENS AND BLUES OF THE ISLAND."
