To select a polyline by colour:
first determine the numeric code for the colour
I can't recall how I did this. Maybe someone else has a good idea here.
But you could create a thematic map with a colour set to the colour you
want and then read the colour number from the mapbasic window at the brush
statement.
then type and execute the following in the mapbasic window for polylines
select * from yourtablename where
str$(styleattr(objectinfo(yourtablename.object,2)4)) = str$(65535)
substitute yourtablename with your table name and substitute 65535 with
your colour code. BTW 65535 is for light blue
Hope this helps
