I've passed all the constructive comments here on to Ged and I know he will take them into account when working on the designs for the next edition. That doesn't mean that we will revert to everything being in black 12pt on a white background but, hopefully, we should avoid anything being unreadable by the majority of readers.
As an aside, it's worth bearing in mind that (a) from what people have said on here, colour blindness is a complex condition and what is clear to one sufferer may be a challenge for another. It's hard to be certain that every reader will be able to read everything easily, so please don't think that it's intentional; and (b) sometimes things don't look exactly as they did on the screen when they are printed.
I will also look into the idea of making the text files of articles available on line, possibly as part of an AUK Archive.
That aside, submissions are invited for the next issue....
