Registration/activation messages on site

The registration/activation messages that appear (an email has been sent to the address you entered + your account is now activated etc) do they get the colour of blue background a pink boarder from Joomla css or Hikshop css?

Basically my question is where do I change the colours?

Hi,

The messages are displayed by your template. You need to look in your template's CSS file in order to tweak them.
