LOGO Interpretation

  • The brand color of DDTOP is bright orange. Orange is a safety color, so we call it "Safety Orange". Because orange is the most conspicuous color in low light, it is also the color of lifeguard and astronaut uniforms.
  • Orange is a mixture of red and yellow in the Chinese flag, which means that we are from China.
  • At the same time, orange represents health and vitality. In nature, the orange color in fruits and vegetables is produced by carotene. Carotene, a pigment, converts light energy from the sun into chemical energy that promotes growth, so orange is often associated with health, growth and flavor. Orange also represents vitality, joy and positive, enthusiastic energy, as well as company, active brain cells that stimulate creativity and innovation.
  • Finally, the color orange represents warmth. Orange is the color of the sunrise, a warm color that makes people feel at ease, and that is the feeling that DDTOP wants to convey to its customers.
