Let's say the following msglist rules are defined:

# default msglist_* styles
msglist_default.fg                     = "#d3d3d3"
msglist_answered.fg                    = "#555555"
msglist_flagged.fg                     = "#00ff00"
msglist_deleted.fg                     = "#555555"
msglist_result.fg                      = "#ffaa00"
msglist_marked.fg                      = "#ffff00"
msglist_*.selected.reverse             = false
msglist_*.selected.bg                  = "#d3d3d3"
msglist_*.selected.fg                  = "#000000"
# dynamic msglist_* styles
msglist_default.From,~Robin.fg         = "#ff0000"
msglist_answered.From,~Robin.fg        = "#555555"
msglist_flagged.From,~Robin.fg         = "#00ff00"
msglist_deleted.From,~Robin.fg         = "#555555"
msglist_result.From,~Robin.fg          = "#ffaa00"
msglist_marked.From,~Robin.fg          = "#ffff00"

Which means that messages under the cursor should always be displayed as black on grey (#000000 on #d3d3d3). However, if a selected message is colored according to the dynamic rule shown above AND is answered (#555555) flagged (#00ff00), a result of a search (#ffaa00) or marked (ffff00, yellow) -- then its foreground color will stay as defined by the corresponding dynamic sub-rule.

Screenshots to illustrate:

• two dynamically colored messages vs two common messages: the cursor is black on grey, which is correct;
• all messages are marked, a common message selected: the cursor is black on grey, which is correct;
• all messages are marked, a message highlighted by the dynamic style selected: the cursor is yellow on grey, which seems to be wrong.
