To raise creatinine levels; eat red meat 4/5 days prior to the test and/or buy creatine monohydrate from a drug store.
To fool SG; drink calcium and magnesium-rich water.
To fool the color; 50mg of riboflavin on the morning of the test (before the voids) will do the trick. Don't take more.

I doubt you did any research though; both your questions can be answered in under 20 seconds looking at the posts on the forum's main page.
