Dear E., As long as you are taking your pill everyday (doesn't matter which color) you're safe. The 7 non active pills are there so you will have your period, but you are protected from day 1 till day 28.
Do not delay taking the next pack (!!!!) If you do this, the first 7 days of your new pack are not safe and you have to use a condom.
Good luck, I.
