Came back after skipping last season, and noticed that ground text labels for items don’t match of one was picked in recolour within an filter.
Interestingly enough, affix indicators do match recolour option in filter… also work well for set/unique items background but not for plain text items.
Solution would be to add option to make text bold, increase font pixels or change(give option) to same font used in filter UI.
UI scale does not make any difference in that regard and it is not an issue with readability.
