iodine
iodine is the only halogen in solid form. so it is the halogen which gives violet vapours on sublimation...
Iodine has violet vapor.
It goes from solid to gaseous form without passing through a liquid phase.
Placing iodine covered in a warm place could cause sublimation to a cool spot on the container - if the temperature is even on the container walls, if the temperature is warm enough the violet colour of gaseous iodine may be visible.

When a bottle containing solid iodine crystals stands at room temperature, it will form a violet haze which is iodine gas. Iodine crystals go through sublimation when undergoing heat. The gas will form back into iodine by placing the bottle in a cooler temperature.

No, iodine is a violet coloured solid on heating it sublimed into violet gas.

"Iodine" means "violet."
The iodine crystals when subject to heat turns to a violet gas , and when it cools it turns black/silver to its original solid form.
Iodine is added as a mordant to enhance crystal violet staining by forming a crystal violet-iodine complex.
It is called iodine because the Greek word for violet is iodes
