How to match red and blue to look good

Quick answer：

Matching red and blue can create a striking contrast that is visually appealing. To achieve a harmonious look, consider using red as an accent color and pairing it with blue tones that are complementary to red, such as lighter blues or pastels. Alternatively, you can opt for a monochromatic approach by using different shades of blue and red within the same color family. It's important to balance the colors and not to overpower either one. For example, wearing a red shirt with blue jeans or pairing a red scarf with a blue sweater can create a stylish ensemble.
