XF 1.1 Reset Master Style Color Palette - It's forcing all the wrong colors

I've accidentally changed the color palette in the master style instead of a child style.

Now I can't get my site back to how it was. I've imported the theme style I'm using again and it has no effect on the colours.

I've done a master reset by going to /forum/install and still the colors are all wrong and I can't get them back to how they were in the blue flexile theme I added.
