Hi Reefy,
We're very limited in the choice of colors for text, so the only viable solution I found was to add text indicators to the items. When you have the colorblind option enabled, you should see visual indicators appended to the item names, such as (U) for unique items.
If you have a better solution (other than changing the color obviously), let me know. You can also use d2stats (see tools section of our website) to setup notifications on particular item types and quality, which may help you further differentiating the items that matter to you.
