I have always enjoyed those posters often found in Irish themed pubs which show scores of front doors or house fronts taken in Ireland. They are always brightly coloured. Of course we use bright colours on our many render-finished houses in Brighton. I’ve painted my share of purple or bright green or bold pink houses over the years, but the Irish go that one step further and mix bold colours.
And I think its because they don’t see enough bright sunlight, and this decorative style helps to make up for the lack of it.
