Resolved Image are brighter in game compared to the source

I load a png from StreamingAssets, but the image are brighter in game compared to the source

Code (CSharp):

1. var tex2d = new Texture2D(2, 2, TextureFormat.RGBA32, false, true);
2. var bytes = File.ReadAllBytes(path);
3. if (!tex2d.LoadImage(bytes)) {
4.     return null;
5. }
6. var sprite = Sprite.Create(tex2d, new Rect(0, 0, tex2d.width, tex2d.height), Vector2.zero, 100);
7.  

Unity 2021.3.15f1

 

There are many things that could cause this..

The first ones that come to mind are:
- Are you using a lit shader?
- Which Color Space are you using? (Linear/Gamma)
- Compression settings?

 

I used default ui material (Image canvas) and I can't configure the picture from unity. Where can this be?

 

Ah, my bad. Compression Settings wouldn't be available if you're loading from disk.
Color Space would be under Player Settings. Try both Linear & Gamma I guess..
You could also try different TextureFormat's.

 

This looks like a good old gamma mismatch result. Usually a hassle to remedy.
You have this option you can try flipping:

If you have access to the source material you can try converting the color profile to something standard like sRGB.

 

Different TextureFormat's and converting the color profile did not give any results. But changing the legacy PNG and the linear argument to false helped. Thanks!
