Photons in the wavelengths ranging from 585 to 620 nanometers existed for billions of years prior to fruiting plants.
But, to PupnTaco’s point, it depends on whether you define color as a physical property or as a mental perception… and if you go with perception, although orange trees are probably older than beings we would identify as human, there wouldn’t be much different about ancestral primates’ color perception than modern humans. Fruit changes color to be identifiable to its intended consumer as ripe, so the animal would first have to be able to distinguish the color to which the fruit was changing before the plant was able to evolve to provide that signal.. so I’m still going with color.
