I have linked a few products to other products but there is a problem.

All my writing is in purple colour.

When you hover over the links the writing changes to red.

However, the links do not appear in a contrast colour within the purple text ie. say a blue colour - so it's not obvious to any potential customers that the link is even there unless they happen to hover over it.

how can I change this?

ps. thanks for your help on my store back up, I now know exactly what I am doing.
