White clothes with a blue background can provide a fresh, natural and harmonious feeling, making family photos look more vivid and energetic. At the same time, blue can also give people a feeling of warmth, tranquility, and comfort, allowing family members to relax and naturally show their truest side.

In addition, if the environment for taking family photos is outdoors or in some brightly colored places, you can also consider using other colored backgrounds, such as green, yellow or pink, etc. These colors can make the photos more vivid and fun. Of course, you also need to choose a suitable background color based on the actual environment and the preferences of family members.
