pixel images have incorrect colors

Help! I’m trying to make my first game, I have a character, but when I put her into Unity she doesn’t have the right colors. I have attached the images below, one is the character in GIMP, and the other is her in Unity. How do I fix this?

Check the image import settings and turn off compression.

how do I do that? I’m new to unity

It is the inspector that appears when you select your image in the Unity Project window.

Google up the Unity manual for Texture Importer.

ok thanks
