Named after the bubbly beverage, champagne is a mixture of yellow and orange and closely resembles beige. Sitting on the inner, paler portion of the color wheel, the warmth of orange mellows the brightness of yellow in it.
Champagne brings to mind the effervescence of the drink. Because the drink is usually consumed in happy events like weddings or New Years, it also evokes feelings of joy.
A borderline neutral shade, champagne pairs well with most colors. It can even be used to highlight yellows and oranges.
