A lila color, from potassium spectral lines.
Potassium will produce a purple color. In a flame test it is sometimes kind of hard to see.
lilac
Potassium chloride
Depending on the metal in the chloride (Na, Ca, Sr, Li, ....).
In this reaction white precipitates of Silver chloride are formed.
No color. When burning chlorine, the flame gains no additional color from the chlorine. Examples of this may be found by burning Aluminum chloride or Magnesium chloride, both of which burn colorless. This means that Chlorine contributes no color to the flame.
When Magnesium chloride is burnt in a Bunsen flame, it imparts no colour in the flame.
When flame tested, Sodium ions range from a yellow to a bright orange flame and Potassium ions give a lilac or light purple flame. Neither the Sulphate nor the Chloride ions should have emission spectra in the visible range.

Potassium.
Color is determined by the respective cation: Potassium - lilac Sodium - yellow Lithium - red
The color is from the potassium !
A lilac-violet color
Purple
Bluish-green
No, potassium chloride contains potassium chloride.
