what's your point? colours are dull/not vivid?
in such case you can try adjusting some settings in your camera.
but the camera won't let you tweak those settings if you were shooting in auto modes(other than P, Av, Tv, M).
if you are using Canon, see it in the picture style menu. you can + the contrast and/or saturation.
if you are using Nikon, it's in optimize image(picture control) under shooting menu.
i don't know other systems:lovegrin:
in fact, your shooting condition, using high ISO..etc..and many others might affect the colors of your pic. many variables to discuss.
the best is to post your pic so that other experienced bros out there will further advise.
