CSS Color Variables from Random Palettes
Once you've generated a palette you like, here's how to use it in your CSS with custom properties for easy theming:
:root {
--color-primary: #3B82F6; /* Main brand color */
--color-accent: #F59E0B; /* Highlights, CTAs */
--color-bg: #F8FAFC; /* Page background */
--color-text: #1E293B; /* Body text */
--color-muted: #94A3B8; /* Secondary text */
}
.btn-primary {
background: var(--color-primary);
color: white;
}
.highlight {
color: var(--color-accent);
}Replace the hex values with colors from your generated palette. Using CSS variables makes it easy to swap entire color schemes by changing just 3-5 values.
