This week, the question comes from Lisa B. in Oak Creek, who sent the following query: "It's getting cold out and my memory is fading. What's the color code for the flame on top of the Wisconsin Gas Co. building Downtown?"

That's a common question, Rachel. Before we answer, a little background is in order.

Although the building was sold to a developer more than five years ago, most Milwaukeeans still refer to the building at 626 E. Wisconsin Ave. as "The Wisconsin Gas Building." Designed in the Art Deco style by Eschweiler & Eschweiler and completed in 1930, the building is 250 ft. tall and has 20 floors. The first 2 ½ stories of the exterior are granite, but the rest of the building is constructed of varying shades of brick. The upper floors are lighter, to give the building a taller appearance.

In 1956, a weather beacon shaped as a natural gas flame was added to the top building. The neon flame is 21 ft. tall and adds a unique splash of color to the Milwaukee skyline.

Known as the "weather flame," the light changes color along with the weather forecast for the following day.

Gold means the weather will get colder. Red means it's going to warm up. Blue means the weather will stay the same. When the light flashes, precipitation is expected.

If you need help remembering all that, try focusing on this rhyme:

"When the flame is red, warm weather is ahead.

When the flame is gold, watch out for cold.

When the flame is blue, there's no change in view.

Where there's agitation, expect precipitation."
