I haven't read all the replies, but I clicked on the various links in your post, and right off the bat, I came up with :
G185 Taupe ...I put three checkmarks next to this pair on my little notepad
G187 Blue ...two checkmarks ...
I also liked the G284 quite a bit, but felt like the pale green (although beautiful) wasn't going to be a real workhorse in terms of your climate and lifestyle.
I love all the shoes you picked out, it's just that I'm not 100% sure that pale green or too much pale blue will work in your climate - I'm guessing that from October to April it's pretty much fall/winter there?
In the meantime though, you have found some fabulous deals! WOW. Now I have to ask - how do these fit? I tend to take a smaller size in Ecco and even Clarks than I do in other brands - would you say that Fidji is kind of similar - as in, you might size up a wee bit? Or are they pretty true to size, in your opinion?
Definitely get G185 in taupe, and if you're just hankering for a different 'colour' - go for G187 in blue. I'm not necessarily good at this though...just giving my non-expert opinion in terms of what I liked and what I think might work with your wardrobe, climate and style.
