I'm designing a color scheme for a web application with a data dashboard. I want the graphs and data visualizations to have a default color palette with distinct colors that maximize the ease of seeing relationships in the data. The app will display a very wide variety of data sets, many of which will require a large number of colors.
I'd like to pick at least 50 default colors. Is there any application like Kuler where you can see color swatches next to each other and you can also pick a lot of different colors? Kuler limits you to 5.
