On many occasions, the color used in the autograph sometimes plays an important role. Generally speaking, black signatures are the most common, indicating people's formal attitude and serious and responsible attitude. Other choices of color autographs may relate to specific occasions or purposes. For example, red is commonly used in celebrations and traditional cultural activities, while blue may be used to express corporate image or personal preferences.

In addition to personal preference and occasion, the color of the autograph may also have some hidden meanings. In some business situations, blue signatures are considered more professional and credible than black signatures, while green signatures show the company's environmental awareness and social responsibility. In art and creative fields, artists and designers may use colorful colors to reflect their creativity and personality.

In some people’s opinion, the color of the autograph also reflects a person’s character and personality. For example, a black autograph may indicate a person's composure and focus, while a red autograph may indicate a person's enthusiasm and confidence. Purple signatures, on the other hand, may reflect a spirit of adventure and a creative way of thinking. Of course, the association between these colors and people's personalities is just a common one, and what's true for each person may vary from situation to situation.
