Possibility to update color theme for different spaces.

Hi,

When working with Storyblok we have a setup with one space for a testing-environment and one space for the live-environment. In a work day we switch between these two spaces very often but as they are very similar to each other there are often mistakes when we publish or add content to the wrong space.

If we could customize the color theme of the different spaces it would be easier to keep track of what space we are currently making changes to and in that way reduce the risk of errors.

Thanks!
