Color Picker
An online Color Picker is a visual tool that lets you choose a colour from a spectrum or enter a colour value and instantly see its equivalent representations in HEX (#RRGGBB), RGB (Red, Green, Blue 0-255), and HSL (Hue, Saturation, Lightness) formats.
What is Color Picker?
Colour accuracy is critical in digital design. Each colour model serves a specific context: HEX is ubiquitous in CSS and HTML; RGB maps to screen hardware and is used in web APIs; HSL is intuitive for designers manipulating hue, saturation, and lightness. This picker lets you select any colour interactively and provides all three formats simultaneously with one-click copy.
Use Cases
- Designing colour palettes for websites and apps.
- Converting client-provided HEX codes to RGB for CSS filters.
- Finding the HSL equivalent of brand colours for design systems.
How to Use It
Click on the colour canvas to select a colour visually.
Or enter a HEX, RGB, or HSL value directly.
All formats update simultaneously.
Click a value to copy it to your clipboard.
Pros
- All three formats shown simultaneously.
- One-click copy for each format.
- Interactive visual picker.
Limitations
- Does not provide CMYK values for print design.
Best Practices
- Use HSL for programmatic colour manipulation (darkening/lightening).
- Use HEX for static CSS values.
- Verify colour contrast ratios meet WCAG AA (4.5:1 for text).
Common Mistakes to Avoid
- Using similar shades with insufficient contrast for text, failing accessibility standards.
FAQs
What is the difference between HEX and RGB?
HEX is RGB expressed in base-16 notation. #FF0000 equals rgb(255, 0, 0)—both represent pure red. HEX is shorter; RGB is easier to manipulate programmatically.
