What color does barium produce?
bright greens
Barium produces bright greens; strontium yields deep reds; copper produces blues; and sodium yields yellow. Other colors can be made by mixing elements: strontium and sodium produce brilliant orange; titanium, zirconium, and magnesium alloys make silvery white; copper and strontium make lavender.
What color flame does barium sulfate produce?
yellowish-green
Barite (barium sulfate) gives a yellowish-green flame. Calcite (calcium carbonate) yields a yellowish-red flame, often described as a “brick red” as opposed to the crimson of a strontium flame.

Why is barium green flame?
The heat of the flame excites the metals ions , causing them to emit visible light. The characteristics emission spectra is used to differentiate between the elements. The emission spectra of barium contains the wavelength corresponding to green colour ,hence barium gives green colour.
