Thanks everyone.
I'd prefer not to change the toaster, kettle etc as they are relatively new (grey) but it is an option.
There are two blinds which we rarely use, they are neutral stripes and are kept up high out of the way. We are very private at the back.
The kitchen window stuff .... I got dh to make the white (removable) shelving so it can hold small bits that are used regularly.... Jugs, spoon rests, a little dish holds a lipstick, reading glasses, odds and ends, flowers from the garden especially the odd broken stem get popped into the jugs. I like it because it's different, saw one in a craft shop and asked dh to copy it.
Not sure about the fablon - it reminds me of years ago when my mother would have used it, there were air bubbles and the edges curled. Perhaps she wasn't too good at putting it on.
The end wall is already a pale green, it doesn't show up well in the pic. The living room is already sage greens which is why I was thinking of continuity with the lime green.
The porch is mint green and I don't like it. Asked dh to get another tin of sage green for it and he came home with mint green which was on offer. Not only that, it was shiny finish. Not wanting to knock his efforts I went with it but to be honest might just be biding my time with it. I guess it's ok but I don't love it.
I think the blandness is the cupboards and walls being the same colour.
Don't fancy a true blue.
Uncertain about a pink.
At the start of this I said definitely not yellow but I'm swaying on that. It seems popular with you GNers, maybe a limish yellow?
I agree with Monica about going for the jackpot and not pussyfooting, but not lollipop pink. (sorry Monica). Getting reminded of the colour of peptobismal medicine
You have all been so helpful.
Perhaps I need to go to B & Q bearing in mind all your suggestions and look at the colour card display.
Who knows I could come home with sunshine yellow or lollipop pink.
