ahh bummer, I'm so sorry,
If nothing will fix it in the wash...I would seriously consider trying to match that miss hap red with a little fabric paint.. And lightly streak the other biege pieces ( or where ever it ran on to)Make it look like it was done on purpose, before I gave up...Or applique/s, something..
If you do decide to go for the paint...I'd get the closest red and also pick up a black and a white paint. To mix in if you need to darken and or lighten to match... You can also add a little yellow to warm up the red or a little blue to cool it...
