Frequently Asked Questions

What is a monochromatic color scale?

A monochromatic color scale consists of variations of a single hue, created by adjusting lightness and saturation. It produces tints (lighter), tones (muted), and shades (darker) from one base color — ideal for cohesive UI design and data visualization.

How does HSL help generate better color scales?

HSL (Hue, Saturation, Lightness) maps directly to how humans perceive color. By keeping the hue constant and evenly distributing lightness, we create perceptually uniform stops that look natural and balanced — unlike naive RGB interpolation which can produce muddy mid-tones.

What's the difference between tints, tones, and shades?

Tints add white (higher lightness, lower saturation). Shades add black (lower lightness). Tones add gray (reduced saturation at similar lightness). Our generator primarily creates tints and shades in the HSL space for clean, vibrant scales.

How many stops should my color scale have?

For most design systems, 7–11 stops works best (similar to Tailwind's 50–950 scale). Data visualizations often use 5–7 stops for clear differentiation. UI hover states may only need 3–5 stops. More than 15 stops are useful for detailed heatmaps or gradients.

Can I use generated colors in Tailwind CSS?

Yes! Use the Export → Tailwind Config option to get a ready-to-paste color object for your tailwind.config.js. The stops map naturally to Tailwind's 50–950 naming convention, making integration seamless.

What is the 60-30-10 rule in color usage?

The 60-30-10 design rule suggests using your dominant color for 60% of the space (backgrounds), a secondary for 30% (sections, cards), and an accent for 10% (CTAs, highlights). A monochromatic scale gives you all three from one hue — light stops for backgrounds, mid stops for surfaces, and darker stops for accents.

Why do some generated stops look less saturated at the extremes?

This is intentional and mimics natural color perception. Very light colors (near white) and very dark colors (near black) naturally appear less saturated. Our algorithm gently reduces saturation at lightness extremes (below 15% and above 85%) for a more professional, natural-looking scale.

Is this tool free to use for commercial projects?

Absolutely. All generated color scales are yours to use in any project — personal, commercial, or open-source. No attribution required. The colors are mathematical derivations from your base input, so they carry no licensing restrictions.
