I wanted to create a stacked bar chart with the colors I've indicated in the color_vector. But it's still printing out the default colors associated with ggplot2.

#create a stacked barchart of proportion
color_vector <- c("lightcoral", "lightblue1", "lightgoldenrod", "salmon", "peachpuff", "pink2", "tan1", "sienna1", "slategray1", "indianred1", "black")
names(color_vector) <- levels(merged_df$trstprl)

ggplot(merged_df, aes(y=proportion, x=cntry, fill = rev(as.factor(trstprl)))) + 
  geom_bar(position="stack", stat="identity") + 
  scale_color_manual(name = "trust level", values = color_vector) +
  ylab("% of each ranking for trust level") + 
  xlab("country") +
  guides(fill=guide_legend(title="Levels of Trust")) +
  scale_fill_discrete(labels=c('10 = Maximum Trust', '9', '8', '7', '6', '5', '4', '3', '2', '1','0 = No Trust')) + 
  ggtitle("Proportion of Trust for Government by Country") + 
  theme_stata() +
  theme(legend.position = "top", legend.title=element_text(size=10))

I've tried using the scale_color_manual but that doesn't seem to be doing anything. I've also tried changing fill to color = rev(as.factor(trstprl)) but that just changes the color of the outline not the entire area of the barchart i'm trying to change

    Not sure exactly what you are trying to do, but I think you need to use `scale_fill_manual` with your colour vector and the labels you defined in `scale_fill_discrete`. You can't have two `fill` scales. – George Savva Dec 14 '22 at 22:21
