Feature Request Summary: 

A bunch of prebuilt Themes (something like Google Surveys maybe?) would make the design element of Dashboards much easier. 

Description/Use Cases: 

I imagine I am not the only person who ends up building a lot of queries, and then Dashboards, because they have SQL skills. I do not, however, have great graphic design skills, or even full color vision. As a result, if left to my own choices, I build some really ugly Dashboards. Add on that about 6 months ago, the default look of a query when you create it, changed vastly, and my Dashboards are a hodgepodge of old style teal headers and new style floating minimalist monochrome boxes. 

Business impact of limitation or missing feature:

Being able to apply a theme to a Dashboard, that would re-skin all queries on it with the same colors, fonts, corner rounding, backgrounds, etc, would make it much easier to produce Dashboards that look slick and professional. This would also make it much easier to "fix" an existing Dashboard if you found out that your schema wasn't color friendly to someone on your team, and make it easier to adjust the accessibility of a whole Dashboard.
