Green would be more original, as the original FireRed, for some reason, chose blue as its main color for palettes, as most things I noticed are very blue. Also, LeafGreen never used green, so it would be a wise choice.
Therefore, since rijonAdventures' main color is green, you should choose green.
Oh, just to add a little suggestion to the green floor, you should make the green floor tiles look more like they are advanced. Maybe round the corners of each tile and then make the green fill in more, like how the blue looked in the past.
