a little color came off my tattoo

I just got my tattoo the day before and i woke up in the morning with my shirt stuck to my back! i slightly pulled it off and i saw a little color came off with the shirt!! Now im scared that the color wont be as bright as it should be because the color wasnt suppose to come off! Is it normal for the color to come off a little?! also how can i avoid for this happening again? especially when my shirt will be on for me to go to work.
