Is it better to have a hotel plaque with white characters on a red background or red characters on a white background?

Red text on a white background is good. Red letters on a white background are better, because red letters on a white background should be eye-catching, and because everyone knows the infrared wavelength of red, people can spot it from a long distance and clearly see what the words are. As for the white characters on a red background, people see red from a distance. The white characters cannot be seen clearly. Only when you get closer can you see clearly what the characters are, so the red characters are the most eye-catching.
