color: #3b82f6;📚 About Color Systems
Three main color formats in modern web: HEX (short hex like #3B82F6), RGB (three 0-255 values), and HSL (Hue, Saturation, Lightness). Each has its use: HEX for quick sharing, RGB for low-level code, HSL for visual adjustments.
Rule of thumb: start with HSL when designing your palette (easy to tweak), save as HEX at the end for simple sharing. For programmatic work, RGB is fastest. HSLA adds transparency for overlaying colors over images or backgrounds.
🎯 Designer tips:
- For harmonious palettes, keep Lightness at 50% and rotate Hue every 30° for complementary colors.
- For active/disabled buttons, drop Lightness by 10-15% for darker shades.
- Avoid 100% saturation for text — hard to read. Use 70-85% for shapes, 50-70% for backgrounds.
❓ FAQ
What is the difference between HSL and RGB?
RGB defines color by three values (Red, Green, Blue) 0-255. HSL uses Hue (0-360°), Saturation (0-100%), Lightness (0-100%) — easier for gradients and harmonious palettes.
When should I use HSL instead of RGB?
Use HSL when adjusting brightness of an existing color, creating gradients with similar hues, or building flexible design systems.
Does HSLA support transparency?
Yes — HSLA adds an Alpha channel from 0 (fully transparent) to 1 (fully opaque). CSS: hsla(120, 50%, 50%, 0.8).
What is the difference between HEX and RGB?
HEX is hexadecimal notation for RGB. #FF0000 equals rgb(255, 0, 0). HEX is shorter and easier to share.
