The clear has 'burned' the colour layer. It's softened it to the point where it has become wet again and then flowed into the wet clear layer. Then all the metallic particles have pooled up. That's why you have that colour shift and patchy finish. The Tamiya TS-13 is renowned as being a hot clear. It can cause decals to melt also. Don't stress, you can strip the paint off with ipa and repaint. If you use the same clear again go very light and allow time between coats..
