What happens when you actually apply color theory
We tracked three redesign projects that used specific color principles. The results show how contrast ratios, complementary schemes, and palette hierarchy affect user behavior.
Each case included A/B testing over 60 days with measurable outcomes in engagement, conversion, and accessibility compliance.
SaaS Dashboard Redesign
Fixing contrast issues in a data-heavy interface
The original dashboard used low-contrast grays that failed WCAG AA standards. Users reported eye strain during extended sessions and missed critical data points in charts.
We rebuilt the palette using a 7:1 contrast ratio for text, implemented color-blind safe palettes for data visualization, and added semantic color coding for status indicators.
