Another addition to the church challenge, and one which I was fortunate enough to visit earlier this month, is the Mariaczka Basilica on the town square in Krakow. The Central Europeans love color in their churches, and the Mariaczka is a perfect example. The whole church is a blaze of hues that, instead of becoming garish, unite in pleasant harmony. You can see this most clearly in the sanctuary, whose altar, ceiling, and choir stalls are shown below.
