comparison
HEX vs RGB vs HSL: When to Use Which
| Format | Readability | Best For | Adjustable by Eye? |
|---|---|---|---|
| HEX (#rrggbb) | Compact | CSS variables, design tokens, copying from Figma | No |
| RGB (r, g, b) | Moderate | Programmatic color blending, canvas API | Somewhat |
| HSL (h, s%, l%) | Most intuitive | Theming, creating tints/shades, accessibility checks | Yes |
All processing happens entirely in your browser using JavaScript. No files, text, or data are ever sent to a server. Your data stays on your device.
✦ tip from dragontail
Dragontail's entire colour system is defined in HSL. The reason: HSL makes it trivial to create a colour palette — you fix the hue and saturation, then just vary the lightness from 10% to 90% to get your full range of shades. Try it with your brand colour: convert its HEX to HSL, then adjust only the L value. You'll have a professional-looking scale in seconds.
faq
What is the difference between HEX, RGB, and HSL?
HEX is a compact hexadecimal notation. RGB specifies red, green, blue components (0–255). HSL specifies hue (0–360°), saturation (%), and lightness (%), which is often more intuitive for design work.
Does it support alpha/opacity?
Currently the tool handles opaque colors. RGBA and HSLA support may be added in a future update.
Is this tool accurate?
Yes. The conversions use standard mathematical formulas and are equivalent to those used by browsers and design tools.
