Red is very eye-catching, and it is rare to see one with red as the background. In addition to KFC, Nestle and other distinctive template designs, most general template designs are mainly light and plain. The first is to highlight words and focus patterns, and the second is to reduce eye fatigue.

Next, I agree with Du Tianshen's Niu Ge that if red must be used as the background color, then black or white is more suitable for font color. Other colors don't mean no, but the contrast must be very sharp. Patterns and font colors should echo each other and have similar requirements.
