When I use an emoji to differentiate a pinned tab in the tab bar, it’s hard to see when it’s not in a hover or focused state. This makes it hard to choose the correct tab when there will be multiple files pinned.
Even white emojis don’t do well, which should be the same as the plus icon or the home icon in the same state, but its not.
Here a white emoji to show hard it is to see the emojis.
Proposal: Don’t darken the emojis, just the background of the tab.
