Wrong colors in default compression settings

hello there. i’m new to UE. got a problem during importing 2d sprites. The problem described in title. So how can i achive correct colors in DXT compression mode? Seems strange, cause other sprites that i imported doing well in DXT… Is it because of colors this sprite using? should i use RGBA instead of DXT? Is it normal? What sprite file format most of developers use? I’m on UE5 Preview 2 version. What I tried:
-turning sRGB on and off
-converting sprite to 8bit

thank you.
