It may seem counter intuitive, but temperature defines the color of an object and the hotter an object is, the more its color will tend towards the left side of the color spectrum. As someone else said before on this site, thinking about heating a metal rod puts things in perspective. As you heat the rod, it glows red and than bluer in color as it heats up. Also, think about the hottest area of a flame--the flame is hotter at the point where it is blue in color rather than red.
