When creating charts Board automatically takes colours for the different series (which is good, especially as you can also manually change them).
However, the values shown from the labels should be coloured in the way that it is visible…in the screenshot below the values in the blue series are not visible - if you hoover of the series it shows the details in white font over the blue box, perfectly visible. The same should apply to the font on the chart (the 12% should be in white and not black).
