New problem
In the NES version of Super Mario Bros. and Super Mario Bros.: The Lost Levels, red enemies stay red underwater, but green enemies turn gray. Why?? I can't find any sources talking about the reason for this. (The SNES version doesn't keep this property; green enemies are always green in SMAS.) Georgia guy (talk) 00:00, 19 July 2019 (UTC)


 * Reds should actually be absorbed by water before greens, so they seem to have it backwards. Unfortunately most creators of video games, movies, TV shows, etc., pay little attention to scientific accuracy. SinisterLefty (talk) 00:18, 19 July 2019 (UTC)


 * The game probably simulated underwater using graphic filter(s) that added blue/green to the scene. The blending of the color with green objects makes them appear gray in part due to a process known as Chromatic adaptation. 107.15.157.44 (talk) 21:44, 20 July 2019 (UTC)
 * I promise you that they didn't use any sort of filter to blend colors together on the NES.
 * The NES could render 64 colors, but not at the same time. At any give moment, the screen is made up of four palettes, each with four colors.
 * I don't know the exact details of the scene you're talking about, but normally different enemies have to share color pallets, so probably that sort of compromise led to the color choices you're talking about. ApLundell (talk) 19:02, 23 July 2019 (UTC)
