Currently we provide access to all the extjs themes ( blue, gray and dark accessibility theme) to our application's end users. We got a request to make the access theme which is dark to be light.

In short, We need to offer the blue and gray themes with the font and sizes of access theme! How can I get / or modify to get the access theme light shaded? I think I have to use the SCSS and other theme building tools. But I haven't used it yet and would like to know if we can achieve this without much coding.

Thanks in advance,
