Decorating A Very Loud Colorful Gazebo

Hello!
Looking for ideas on how to cover up a very loud/colorfully painted gazebo at a local bed and breakfast for an August wedding. There is painted design on every inch, every spindle, every pillar, everything! Help.... It would be easier just to paint the whole thing white. There isn`t enought toole or $$$$ to cover it all up with just that alone. My colors are lime, white and purple.
