Thank You For Being Available. I Am Using Cymbalta 60mg

Thank you for being available. I am using Cymbalta 60mg caplets. The last prescription came with capsules that were dark blue on one end and a green color on the other half. My present prescription came with pills the are the same dark blue on one half and the other is a beige color. Does this change in color mean a change in the contents? Should I call the pharmacy from which I purchased this medication?
