UE4, Can't create blue background sprite

**UE 4.14.3, 2D Side scroller, **

I’m just trying to make my blue texture into a sprite, but everytime I try do do this the sprite ends up as a different color (green).
Every other texture is working except this.
Can someone help me? :frowning:

i found out how.
create a white background
and then you can change color in the sprite color picker
