Choosing a color combination is one of the most important steps in building a digital interface. Colors aren't just decorative: they guide the user through the layout, define the visual hierarchy and express the brand's identity. This online color palette generator lets you find harmonious, ready-to-use combinations in a few clicks.
To build a solid, balanced design system, it's worth following the 60-30-10 rule: 60% of the space goes to a dominant color (usually neutral, or the background), 30% to a secondary shade (giving structure and contrast) and 10% to an accent color, ideal for drawing attention to call-to-action buttons or interactive elements.
With this tool you can test the accessibility of your combinations in real time against the WCAG 2.1 guidelines, making sure the contrast ratio between background and text (AA or AAA) is high enough for comfortable reading by everyone, including users with visual impairments. You can export your palette straight to CSS variables to paste into your stylesheet, speeding up the jump from prototyping to actual development.
