what color were the first electric christmas tree lights

The first electric Christmas tree lights were introduced in 1882 by Edward Johnson, who created a string of electric lights made of red, white, and blue bulbs. These were the first electric lights designed for use on a Christmas tree, and they quickly became popular due to their durability and bright, colorful glow. Over time, the color palette of Christmas tree lights has expanded to include various colors, including green, blue, yellow, and multi-color lights. However, the classic red, white, and blue color scheme of the first electric Christmas tree lights remains a popular choice for many people today.
