Peppers change color as they near their ripe stage. Check the 鈥渄ays to maturity鈥 on seed packets or in catalogs for a guideline for your particular variety (such as 鈥楤ell Boy鈥 bell peppers mature in about 70 days). This will be the time when the pepper is at the peak of maturity, and fully colored. If you want your peppers immature (for different crispness and flavor), pick them earlier. Some peppers will start coloring up different colors before their final color (such as turning from yellow-green to yellow to orange to red). Timing, though, will depend on variety and local conditions.
