How to use PS to take a photo with a house number

First put both pictures into ps (after putting them in, there are two layers). After that, drag the picture of the house plate directly to the picture of the door, and put it in the correct position. After adjusting the position, the color tone of the picture will be unified. Then you can use ctrl+u to bring out the saturation/hue and adjust the hue of the entire picture. Follow these steps and it should be OK!
