Amazon QuickSight now allows you to add themes and customizations to match your corporate branding or application look and feel. Themes allow authors of QuickSight dashboards to customize their preferred background, text, data, and gradient colors as well as spacing and borders of visuals. See here to learn more.
Amazon QuickSight also now supports conditional formatting in tables, pivot tables and KPI charts. You can customize text and background colors based on field values in the dataset, using solid or gradient colors. You can also display data values with a set of supported icons based on applied conditions. See here to learn more.
Other customizations include synchronizing axes on combo charts to align scaling for both line and bar dimensions, a new color picker to select customer colors in your dashboards, ability to rename published dashboards, and font size customizations for axis labels, tables and KPI charts.
All these features are now available in Enterprise Edition and Standard Editions in all QuickSight regions - US East (N. Virginia and Ohio), US West (Oregon), EU (Frankfurt, Ireland and London), and Asia Pacific (Seoul, Singapore, Sydney and Tokyo).
