First post a black and white photo:
The effect after coloring:
1. Convert the image from grayscale mode to CMYK mode. Duplicate a new layer and work in the new layer later.
2. Select the cyan channel, reduce the contrast and increase the brightness. The color of a person's skin can be revealed. If you are not satisfied, you can use other means to adjust it.
3. Select the CMYK channel and create a new snapshot.
4. Click Snapshot 1 and increase the blue component through color balance. Create a new snapshot.
5. Click Snapshot 1 and increase the green component through color balance. Create a new snapshot.
6. Click Snapshot 2 to return to the orange screen. Now use the history brush to draw hair and click the leftmost space of the blue snapshot to start. Select a larger size for the large area history brush tip and a larger opacity. Select a smaller point on the pen tip at the junction and a smaller opacity. You'll immediately feel the power of snapshots and history brushes. (The hair here is bluish, you can say it is something else) The background is a green snapshot, the same principle.

7. Use Snapshot 1 to restore the white part of the eyes and add a little bit of blue, outline the lips with a lasso, select 1 for the feathering value, and adjust the red point. Use Snapshot 1 to reduce the opacity of the eyebrows, and do this a few times. Not much else to say, the history brush should be meticulous in the intersection. Zoom in a little bit, the size of the pen tip should be moderate, and the opacity should be small. Repeat it a few times, and you can also use two snapshots alternately, so that the intersection is very natural.
