The brands of scarlet letter on blue and scarlet letter on white are beautiful.

Direct comparison is not appropriate. This question is subjective, because different people have different aesthetic preferences for color and typesetting, so we can't generalize which is better. But we can analyze it from the following aspects: color matching: the matching relationship between brand color and font has a great influence on the visual effect of the whole logo. The scarlet letter with blue background and the scarlet letter with white background are common collocation methods, but which one is better depends on the specific use and design effect. Design style: Different colors and typesetting methods will present different design styles. For example, a scarlet letter on a blue background may show a more stable and calm feeling, while a scarlet letter on a white background may show a more concise and clear feeling. So which one looks good depends on whether the design style conforms to the brand positioning and concept. Brand image: brand image and market positioning will also affect people's aesthetic evaluation of signs. If a brand wants to convey a high-quality, high-grade image, it may be more appropriate to use the red letter on a blue background. If a brand wants to emphasize the image of youth and fashion, it may be more appropriate to match it with red letters on a white background. To sum up, both the scarlet letter with blue background and the scarlet letter with white background have their own characteristics and applicable scenarios, and which one looks better depends on the specific situation.
