When searching for an item in inventory, some items are darker than others and do not stand out when the search filter indicates them, and some items are quite bright even when the search filter darkens them.
For example, the unique gloves Rule Of The Simoon is as dark as many other items when the search filter is darkening them. The unique gloves Hand Of Judgement and unique relic Ashes Of Orchirian are very bright, and when filtered they look as bright as an unfiltered Rule Of The Simoon.
I suggest that more be done to make searched-for items apparent, like a brightly colored border around the item.
