Customers often want to set the background color of analytic visualizations such as the ProClarity charts & grids, to match a corporate or dashboard theme. Unlike the ProClarity charts & grids, it's not possible to set the background color of the heat map visualization within ProClarity Professional... it's always a cream color... but it can be changed through a simple modification to the PAS server CSS files.

Cream should be on the list of banned colors, along with sea foam green and salmon.

The color is defined per-language in <PAS virtual directory>/<PAS language>/src/treeview.css:

body {
    height: 100%;
    margin: 0px 0px 0px 0px;
    padding: 0px 0px 0px 0px;
    width: 100%;
    background-color: #ece9d8;
}

Feel free to change it for each language pack. Although it's unlikely a PAS service pack or hotfix would update this file, you may have to re-apply the changes after installing a SP or hotfix.

The downside to all of this is it's a global change, affecting all heat maps rendered by the PAS server. I have visions of using URL-rewrite to make this dynamic per heat map instance, but unless someone wants to make my vision reality, that's all it is for the moment.
