Hex Color Calculator
Hex Color System:
- Format: #RRGGBB (Red, Green, Blue)
- Each channel: 00-FF (0-255 in decimal)
- Short form: #RGB expands to #RRGGBB
- Example: #FF0000 = Pure Red
- Used in web design, CSS, and graphics
Colors play a critical role in web design, branding, UI/UX, printing, and digital graphics. A single wrong shade can reduce readability, fail accessibility standards, or weaken visual identity. That is why designers, developers, and marketers need a reliable way to convert, analyze, and understand colors accurately.
The Hex Color Calculator is a powerful all-in-one tool that allows you to input a color in multiple formats and instantly see its full breakdown. Whether you start with a hex code, RGB values, HSL values, or simply pick a color visually, this calculator converts it into all major color systems and reveals deep insights such as brightness, luminance, contrast ratios, color schemes, and accessibility information.
This tool is ideal for designers, students, content creators, and anyone working with colors.
What Is a Hex Color Code?
A hex color code represents colors using a six-digit combination of letters and numbers preceded by #.
Example:
#FF0000→ Red#00FF00→ Green#0000FF→ Blue
Each pair represents the intensity of:
- Red
- Green
- Blue
Values range from 00 (no color) to FF (full intensity).
The calculator also supports 3-digit shorthand hex codes, such as #F00, which expand to #FF0000.
What the Hex Color Calculator Can Do
This tool does much more than simple conversion. It provides:
- Hex, RGB, HSL, HSV, and CMYK conversions
- Live color preview
- Component breakdown (decimal, hex, percentage)
- Brightness and luminance analysis
- Light and dark color variations
- Complementary, triadic, and analogous schemes
- Web-safe color detection
- Contrast ratio checks for accessibility
- Basic color name recognition
All results appear instantly in a clean, easy-to-read layout.
Input Modes Explained
The calculator supports four different input modes, making it flexible for every workflow.
