Blue Spell Bug

Played 3 games last night... I did log out after first two and it happened again. The first game I was on Janna and blue squares were being casted at me. The 2nd match I was on Janna and the shield at 2nd tower gave me a blue shield and my tornadoes were blue. The third match I played on TF and my cards were blue it was very annoying because I couldn't see the card colors.
