The correct answer is: Natural dyes.
Rogan art is a traditional textile art form from Iran. It involves hand-painting fabric using natural dyes. The dyes are made from a variety of plants and minerals, and they are applied to the fabric using a brush. The designs are often geometric or floral, and they can be very intricate. Rogan art is typically used to decorate clothing, home furnishings, and other objects.
Oil-based paints are not typically used in Rogan art, as they can damage the fabric. Vegetable-based colors are also not commonly used, as they are not as vibrant as natural dyes. Gold thread is sometimes used to add embellishment to Rogan art, but it is not an essential part of the process.
