The commonly used coloring materials in violin paint include colored resins such as dragon blood and rattan, wood extracts such as rosewood and sawwood, plant root extracts such as madder and turmeric, as well as flower and bud extracts such as saffron and gardenia. Some plants are more prone to fading, while others are less prone to fading. However, it is interesting that some colors that are prone to fading when used alone become less prone to fading when paired with other colors.
