Consider using a different color palette based on the format
With !1007 (merged) a color palette has been introduced for the bars in answer statistics. Previously, all bars (except abstention) were rendered with the same color.
For formats with a specific relation between answers (opposites or scale) like it is the case for Y/N and likert it might be better to use another palette to visualize the meaning of the answers. E.g. blue color tones for positive options and red tones for negative options.
