I have looked into the documentation and found that we can only precompile the SCSS files with required colors. And, I am not able to find a way to importing single SCSS file and changing its color in runtime using CSS variables as in Material.
Telerik Recommended Way:https://www.telerik.com/kendo-angular-ui/components/styling/custom-themes/
Material Way:

I have tried it but I am not able to implement such using Telerik theme. So, please confirm me whether Telerik have the support for this or have any plan for this in future.
