I need to add more colors to my charts. The theme builder only has 7 colors. I can see in the exported file that they are in the root under --kendo-color-series a though g. I have tried adding --kendo-color-series-h but my charts won't use that 8th color. I know this is the right place cause i can change the first 7 colors and see that change. So how do I add more colors to the kendo color series?
