Barium produces a light or apple green flame when held in a hot clean burning gas flame.
it could be confused with the different green flames produced by copper, boron, molybdenum, antimony, tellurium, thallium, phosphorus and others.

Strontium chloride creates the red of road flares, lithium chloride also produces a red flame. Calcium chloride is supposed to produce red, but is perceived as a deep orange flame.
i think chemical change
it turns into a blue flame by changing the air valve on a Bunsen burner.
The copper wire glows red. Once it cools...the copper reacts with the air to produce copper(II) oxide. This is shown by the black tarnish on the copper wire.
Oxygen (O2)
Sodium (Na)
Copper (Cu) is the element that turns green when exposed to moist air.
Potassium although sometimes it can look purple
Oxygen turns copper green.
the color of mercury is gray it has no color

The Statue of Liberty is made out of a copper element. When copper erodes or is exposed to oxygen progressively, it turns green.

Nearly all are like that, green at first.
