FB banner tested on my site
The green is now the right colour: and in the right position. I asked the Giselle why it was that in illustrator the colour was right but when you could see it on the fb banner it was the wrong green. It was because illustrator and JPEGs and the internet don't particularly get on all the time because of the quality.. So its not saved as a tiff on high quality for the internet and its now in rgb mode which has helped sort the colour out.
This is it without the logo on the main banner.
