How to Merge Layers in Photoshop?

Question

Adobe Photoshop

The fact is that when I merge the layers I need (for example, a logo), the picture changes its color. Why is this happening?

Answer 1

One of the layers has been applied effects or some other settings.
To merge such a layer with another, you can simply save the effect layer as a separate image, open it and place it above this layer. Then merge with the one with which it was necessary to merge, but not the first layer, but a separate image.
You can also merge layers using a mask. Then there will be no such effect. Try it. There are a lot of ways. Your preference and ease of use will play an important role here))

Answer 2

Most likely due to overlay effects.
Try to achieve similar effects without overlay effects, then 100% no problems will arise.
