Texture Not Showing Correctly in Engine

Hi, so I’m making a game that uses very small (8x8 pixels) textures. When I import them into UE4 however, the colours change - as you can see in the attached image, the imported colours on the left do not match the correct colours on the right. Any idea why this might be? I’ve tried changing various different compression settings but can’t get it looking right.

This is due to Texture Compression.
Set your Texture Compression to “UI”
