How to change the color balance on every photo on a nikon d3000?
I no i can change it after i take a picture by going to the retouch menu, but is there a way i can change the color balance so it stays like that for all of the pictures i take?
Most of us usually shoot in no more than one or two different lighting situations during one assignment.
The "retouch menu" is really just for fun and not there to do all your post production. Lightroom or Photoshop is used to do that and in Lightroom, you can do hundreds of shots at a time.
Initial white balance is done using the white balance feature in the cameras menu. See page 82 and 83 in your user manual
IF you are shooting inside under fluorescent lighting, you need to set the white balance for one of the fluorescent lighting choices and there are a number of them. Shoot a white piece of paper and test each setting until you get the closest one.
IF shooting outdoors in bright sun, choose that white balance while you are shooting under those conditions.
Those of us who shoot professionally use a custom white balance device like Xrite Colorchecker Passport
Here is how it works.

Fhotoace has a good point, a proper whitebalance settings beats editing.
Try your presets. If that fails you can use a special device but even shooting a custom whitebalance from a simple piece of plain white paper will already be a 98% improvement.
