As always, many thanks to each and every darktable developer involved in the process of creating this software gem.
Great tools come with great responsibilities. 
darktable is growing and improving with the inclusion of new tools and the improvement of others in each version.
For this version 4.2 I made some adjustments to my personal theme. But as I wrote in my first message of this post. This is a free personal version that I know does not follow the rules and guidelines advised by the developers to avoid visual mismatches in terms of contrasts, etc. to avoid the negative effects generated by optical illusions
I’ve left two screenshots of the appearance of the theme in this new version.
