Answer in Details
According to the traditions and teachings related to Lord Shiva, the color most associated with Him is ash (vibhuti) or white, symbolizing purity, detachment, and the transcendence of material desires. Lord Shiva is often depicted with His body smeared in sacred ash, wearing simple tiger skin, and sometimes adorned with rudraksha beads. He is also called "Digambara," meaning "clad in the directions," indicating His detachment from worldly possessions, including clothing and adornments.Additionally, Lord Shiva is sometimes associated with the color blue due to the legend of Him consuming the poison (halahala) during the churning of the ocean (Samudra Manthan) to save the universe, which turned His throat blue and earned Him the name "Neelkanth."
So, the colors most connected to Lord Shiva are ash/white and blue, each carrying deep symbolic meaning in Shaivism.
