That makes sense. Thank you for your explanation, it really helped me.

Great. Thank you. When I used a Fill Layer it actually worked. But why is there a difference? Or what is the difference between pixel and fill layer? And are there any other layers where I also have to be careful?

Hello, I got a small problem. Also have I never used any kind of image editing software before. That's why I might need a while to understand. If I don't express myself well enough please tell me. I'll try again. I added a gradient layer in photo persona. Like the on in the picture down below. When I was kind of done I clicked somewhere else. Afterwards I thought about changing it up again. Just a little bit. But I couldn't get in there again. Everytime it added a completely new gradient layer. But actually I just wanted to change the colors a little bit. Can anyone of you tell me a way to change the gradient pixel layer after I was done editing?
