What colour stands out best in a CD shop?

This question is one of the main features which I think is important as normally the colour of something makes you drawn to it which makes you interested. If I chose a colour that was not appealing and did not stand out then our CD would just blend into the background and not stand out, this is important today as there is so many CDs and lots of competition along with that so we need to make sure ours stands out on the shelf. The colours that were voted for the most were yellow and purple, we have not yet decided what we are going to choose but we will definitely choose one of these. We are intending on making ‘The Chasing’ title in black bold writing then have one of these colours in a distort outline which may be a bit blurred. We think this will look appropriate and eye catching on a CD shelf as we are going to make sure that along with the title the image is going to be eye catching also.
