Frequently Asked Questions

What is a complementary color scheme?

A complementary color scheme uses colors that are opposite each other on the color wheel. This creates a high contrast, vibrant look that is great for highlighting important UI elements like buttons.

What is an analogous color scheme?

Analogous color schemes use colors that are next to each other on the color wheel. They usually match well and create serene and comfortable designs, often found in nature.

How do I use the CSS Variables export?

Select the "CSS Vars" export option, click copy, and paste the code into your stylesheet (usually inside a `:root {}` selector). You can then use those variables throughout your CSS like `background-color: var(--color-primary);`.
