Hi sddaffodil,
Thanks for your interest in Essential JS 2.
We are currently working on ThemeStudio support for Essential JS 2 components and it is expected to be rollout by the end of this month.
However, we have implemented a simple node.js application to generate the custom styles for Essential JS 2 components, Please find the below link for further reference.
For example, we can change the $accent color value of material (styles/definition/_material.scss) theme to generate the custom styles as per your requirement.
Please let us know if you have any concerns.
Regards,
Saranya Murugasamy
