I have no data on that particular model, but Kohler is not a highly recommended brand by the pro plumbers that frequent this forum. One of the major problems seems to be the innards of the tank are frequently one of a kind, only available from Kohler, and are extremely expensive. Another brand not recommended is American Standard due to quality control issues. You might want to peruse the forum on these two brands before buying either. Toto is the brand most here recommend and install. I don't know if Toto color choices would fit what you are looking for, but the performance of any of their models is unmatched.
