Frequently Asked Questions

What is a complementary color scheme?+
Complementary colors sit opposite each other on the color wheel (e.g. blue and orange), creating high contrast and vibrant combinations.
What is a monochromatic palette?+
A monochromatic palette uses a single hue at varying lightness and saturation levels, producing a cohesive, low-contrast look.
Can I lock colors while generating new ones?+
Yes — click the lock icon on any swatch to keep it fixed, then regenerate to get new colors for the unlocked swatches only.
