A free offering that is part of a larger for-fee UI course, this palette generator is a handy online tool that quickly creates a set of colors especially designed to make any data visualization, such as pie charts, bar charts, and maps, more effective. Data Viz Palette is similar to Happy Hues (featured in the 04-17-2020 Scout Report) and other online color pickers out there in that users can select criteria, quickly generate a set of colors, and then either copy the color hexcodes or export as SVG for use in a project. Options include palettes, single hue, and divergent, with three to eight colors. It is also possible to click into the color blocks presented and change the range of colors, for example, from blues to golds. A bonus feature of the site is that, unlike some other color pickers, Data Viz lets users see what their colors look like on a dark or light background. However, the platform does not check for accessibility. Users should be careful about the potential to generate a color palette with very dark colors on a very dark background (and vice-versa), resulting in a lack of contrast that might be difficult for some viewers to perceive. Other online tools, such as web accessibility contrast checkers, can help out there.
