where it says this in the script:
@name_spr.bitmap.draw_text(0,0,100,30,@character.name,1)
above it put this in:
@name_spr.bitmap.font.size = 24
@name_spr.bitmap.font.name = "Arial Black"
@name_spr.bitmap.font.color = Color.new( 255, 255, 255, 240)
change those values to what ever you want.
color is controlled by (R, G, B, Opacity)
