Dear list, I'm using pgfplots to create some bar charts with error bars, and I want to use custom colours for them. This works, but if I mix a custom colour with another colour, it results in a gap between the error bar line and the error bar mark. If two custom colours are mixed, the gap seems to be doubled. Mixing with predefined colours works normally. MWE: \usemodule[tikz] \usemodule[pgfplots] \definecolor [Blue] [h=3465a4] \definecolor [White] [h=ffffff] \pgfplotsset{compat=newest} \starttext \starttikzpicture \startaxis[ybar, error bars/y dir=both, error bars/y explicit] \addplot+[blue!50!white] coordinates {(1,5) +- (0,3)}; \addplot+[Blue] coordinates {(1,5) +- (0,3)}; \addplot+[Blue!50!white] coordinates {(1,5) +- (0,3)}; \addplot+[Blue!50!White] coordinates {(1,5) +- (0,3)}; \stopaxis \stoptikzpicture \stoptext Kind regards, Joshua Krämer
