Sprite image on UI appears much darker than actual image file. Please help!

Hey! I created a png image with gimp for some UI background and put it on an image object sitting on a canvas. But it’s colors appear much darker, that the actual image I created is. Does anyone know how to fix this?

Please look at the screenshot for a comparison


Solved. I am so stupid it was the color of the image which was set to grey on default.
