In China culture, red is associated with fire, enthusiasm and prosperity, but in Feng Shui, red is regarded as a symbol of wealth, pressure and conflict. Therefore, red frames may be considered unlucky.
Green is associated with positive meanings such as life, health and hope. However, from the perspective of geomantic omen, green frames may bring instability or adverse effects to people.
It should be noted that different cultures and regions may have different interpretations of the symbolic meaning of colors. Therefore, unlucky colors may vary according to regions and cultural backgrounds. In addition, personal beliefs and traditions will also have an impact on this issue. Generally speaking, it is best to choose the color of the frame according to one's personal hobbies and one's own cultural belief background.
