Feldspar is a group of minerals that can vary in color due to the presence of different elements. However, the most common color of feldspar is white or colorless. It can also occur in shades of gray, pink, brown, yellow, or green.
Sulfur, on the other hand, is a chemical element and is typically yellow in color. However, sulfur can also appear in other colors such as green, red, brown, or black. The color variations in sulfur are due to impurities or chemical reactions with other substances.
So, in general, feldspar is not typically associated with sulfur in terms of color, as feldspar is commonly white or colorless while sulfur is usually yellow.
