For a children's room, light, soothing colors are preferred: white, beige, pink. Bright, exotic colors can only be used in compositions with pastel colors.
There are also several requirements for practicality: it is desirable to make the ceiling easy to clean, made of materials that are safe for the child, light pastel colors (blue, pink, white, light green), especially if the room faces north.
You can paint the walls in brighter colors or create an accent on the wall that attracts attention and leads the eye away from the ceiling - photo wallpapers, panels, carpets, an insert of combined wallpaper with a bright pattern. A wall covering with a vertically oriented pattern will also visually increase the height of the ceiling.
Glowing stickers on the ceiling look most spectacular in the children's room.
If you plan to create a night sky on the ceiling, the star stickers should be luminous. It is also better to purchase space-themed stickers. On a white surface, such decorative elements will become almost invisible during the day, but at night they will glow beautifully.
