❓ Frequently Asked Questions

What does this tool do?

Enter any color value (Hex like #FF0000, RGB like rgb(255,0,0), or HSL) and instantly see the color preview, CSS standard color name (e.g., red, coral, skyblue), and the closest matching color name. 150+ CSS color names supported.

What input formats are supported?

Three formats: 1) Hex: #FF0000, #f00, FF0000 (with or without #); 2) RGB: rgb(255,0,0), 255,0,0; 3) HSL: hsl(0,100%,50%). Auto-detects format — no manual selection needed.

How are color names matched?

The tool uses a built-in database of 150+ CSS standard colors. It calculates Euclidean distance in RGB color space to find the closest color name and displays the match percentage (0-100%).

Why can't I find an exact name for some colors?

CSS only defines ~150 named colors, but humans can distinguish ~10 million colors. Most colors don't have exact official names. The tool shows the closest CSS color name with match percentage.

Why use color names in web design?

Using color names (instead of hex values) in CSS improves code readability. color: steelblue is more intuitive than color: #4682B4. Semantic color names aid team collaboration and maintenance, though rendering may vary slightly across browsers.
