Recent Changes in Unread Forum Graphics

Up until very recently, when viewing the forums, unread sections would appear as a large clear red maple leaf that was easy to see.
Read sections would appear as a greyed out dialog icon.

This was an easy to see system.
Recently this has changed to a grey or light blue dialog icon that are only very slightly different hues.
It takes a lot of peering and concentration to differentiate this same icon in such slightly different colours- that I have to give up and keep randomly clicking with no idea if sections are read or unread.

Please restore to a system of different icons and widely different colours for read/unread sections.
