Hallo @bramam. I can't remember what topics we've had, so I'll try something and hope that it will be acceptable and not a repeat of a previous topic. Please let me know. Danke sehr.
(Thanks @lelensp. I tried to think of something in which everyone could join without too much difficulty. Think we'll go with three, as there are lots of colours starting with D without the "deep" or " dark" ones.)
