I am using the Sass ThemeBuilder to regenerate stylesheets with the themes that we use on our site in order to get the latest version of the styles. One of those styles includes the color Blue Gray. I am able to select and download all other styles and colors except for when I select Blue Gray. When I select the color and click download I receive the a `500 - Internal Server Error`.

The Theme Builder section of the website does not produce a CSS file that contains the styles for the new Skeleton component.

When you start theming using the Bootstrap as a base, change the pallet colours and click download the ThemeBuilder throws. 

Hello,

We want to create a custom Material theme for our ASP.NET Core web application. We are using the Sass Theme Builder but can only select predefined color swatches for the "Material" base theme. We would like to be able to set custom colors per "subject" just like you can with the "Default" and "Bootstrap" theme. 
Is this possible or are you blocking this on purpose for some reason?

Thank you in advance.

We need a way to load/save themes.  The theme editor is honestly not very useful as it is.  This surely can't be hard to allow a user to upload a file and use that as the basis for making changes.  A one-off configuration is not how development works.  There was one ticket similar to this that was marked as fixed but bookmarking and loading from a page is a poor and easy way out way to do this imho.
