These are the dark blue, dark red, dark green, dark amber (gold), yellow, rich color, and look really fantastic! Match perfectly the solid on colored lights. This is a hard plastic colored case around a single LED. If one goes out, the rest of the strand keeps lit! Replaced out all of my old incandescent bulbs with the LED C7 three years ago and no problems with any of the LED bulbs. I am a residential customer that wanted the look of a professional install and I totally accomplished with the help of Novelty Lights. Radically reduced electricity use when I changed. Used a mix of constant on with twinkle and really, really like the look. Highly Recommended!
