paint

Hi everyone, hope someone can help me. I bought a 2006 GMC sierra 2500 and I cant figure out what color it is, I need to color match a few things. I will include pictures in the post so you all can see. The paint code on the door jam is rubbed off. I bought some "original gm color" paint in...

I have a white 2006 duramax(see picture) with chrome rims and a lift on the way, i am getting bushwacker pocket style fender flares and i am debating on painting them white to match or a diff color and paint the whole bottom to match. any suggestions?
