Bright glowing ice blue and white lights then fiery orange appeared

Was walking my dog in the field when he started barking and looking at a wall, I then saw like an oval shape of ice white and blue looked like glowing coals on the floor, I was very nervous at this time and started backing away as it was very dark and didn't know if a person was present, I then thought I've never seen that before so I turned round for another look as my dog was still barking with that I then saw a very bright fiery orange light light up was like a ball shape. With that I got very scared and went home but havnt been able to get this sighting out of my head since.I wish I had my phone with me at the time but had left it at home.
