I put up samples of Bunglehouse Gray (left) and Balanced Beige (right) up side by side, and I'm still undecided. On the one hand, I still like Balanced Beige, and it's definitely a safe color to go with - it'll look good with our other colors, and it's so neutral there's nothing objectionable about it (although it could be argued that being too neutral is objectionable). On the other hand, the Bunglehouse Gray would make the house more Greene and Greene-like. The Gamble House is one of the inspirations for this home, and I think the Bunglehouse Gray gives it more of that feel.
I've got a day or two to sleep on it, but I'm leaning towards the Bunglehouse Gray. But I do like that Balanced Beige... Arggh!
