PNG images becoming transparent in unity?

Im creating this little game for android and IOS, its a 2d game and I make all the images that are used in it in paint.net(the program). However when I import the PNG files to unity and put them in my scene, its almost as if the alpha has been lowered. To better illustrate what Im talking about here`s a picture of it:

If you look closely you can see that the cloud is visible through the dragon type thing(dont judge me). I was wondering if there was a way to fix this. I promise that every alpha associated with the image of the dragon is set to 255.
Any response would be much appreciated!

The alpha on your dragon thing must not be 100 percent solid, and that is why it draws the cloud slightly behind it. Maybe try going into paint.net and checking your drawing with opacity set to fully solid (I haven’t used paint.net in years couldn’t tell you exactly how).

If this problem persists, maybe import the image into regular old paint and see if you still see the problem like it appears in unity. This will confirm paint.net is leaving that purple color a little bit transparent.
