Best regards

Hi Kristjan Einarsson,

The default palette of our Summer theme is as follows:

<SolidColorBrush Color="#FF168BAC" />
<SolidColorBrush Color="#FFA9DB18" />
<SolidColorBrush Color="#FFE8D34C" />
<SolidColorBrush Color="#FFB38DC8" />
<SolidColorBrush Color="#FF58BCE0" />
<SolidColorBrush Color="#FFCCCCCC" />
<SolidColorBrush Color="#FFADE4B3" />
<SolidColorBrush Color="#FFA4A3A3" />
<SolidColorBrush Color="#FF5FB26B" />
<SolidColorBrush Color="#FF717070" />

In my opinion the best way to achieve the desired transparency is to add a custom pallette based on the default one but with changed alpha channel. Here is an example:

<telerikChart:RadChart.PaletteBrushes>
    <SolidColorBrush Color="#7F168BAC" />
    <SolidColorBrush Color="#7FA9DB18" />
    <SolidColorBrush Color="#7FE8D34C" />
    <SolidColorBrush Color="#7FB38DC8" />
    <SolidColorBrush Color="#7F58BCE0" />
    <SolidColorBrush Color="#7FCCCCCC" />
    <SolidColorBrush Color="#7FADE4B3" />
    <SolidColorBrush Color="#7FA4A3A3" />
    <SolidColorBrush Color="#7F5FB26B" />
    <SolidColorBrush Color="#7F717070" />
</telerikChart:RadChart.PaletteBrushes>

Please try this approach and let us know if it is not appropriate for your scenario.
