I am trying to plot Conservative Vote % per borough for London using tmap however the legend colours boroughs with a high Conservative % as light blue and boroughs with a low % of conservative votes as dark blue. How do i reverse this scale so that areas with the most Conservative votes are darkest? 

my code is as follows;

tm_shape(lndbor) + tm_polygons("CON", style = "kmeans", palette = "-Blues", title = "Conservative Vote (%)")
