Why are there different colors in the birth control pack?

Different colors in a Birth Control pack often indicate the different types of pills included, such as active hormones and inactive (placebo) pills. The active pills contain hormones that prevent ovulation, while the inactive pills are typically sugar pills taken during the last week to allow for a withdrawal bleed. This color-coding helps users easily identify which pills to take and when, ensuring proper adherence to the regimen. Additionally, the design can help prevent confusion and support the user in maintaining the correct schedule.
