I have a red-green colour vision deficiency, which makes it especially hard on a typical 13" Mac laptop to see, whether e.g. the Record-button and others are on or off, etc.
In my opinion, and for my eye-sight, there is not enough contrast between the various elements, buttons, lettering og the Logic interface.
There are Web Content Accessibility Guidelines (WCAG) for color contrast and how to use color for color-blind users, and there are color contrast analyzers online, by which one can test that there is enough contrast from one element to another.
So my suggestion is to update the user interface to make all elements of the Logic GUI easier to see for everyone.
