Good point, xij. I'd forgotten (or more likely, didn't know) about the strawberries. I still don't think any particular colour is intended, though.
I wish setters would use "shade" or "highlight" (is there a difference? I don't know) rather than colour, unless there is an obvious relevance to the colouring as in, for example, a national flag. Still, that didn't spoil a hugely enjoyable puzzle. This has been a good year for Listeners, if nothing else!
