^{Originally posted by **yceballost** October 14, 2022} Today is the day. # Context Now, rowlist subtitles are using textSecondary as a color but in cards subtitle color is textPrimary   # Problem Inconsistency in subtitles between components (rowlist and cards) Should we modify the rowlist subtitle color to keep consistency with the subtitle hierarchy across the different components? # Proposal Use textPrimary in rowList subtitles
