Color Formats Explained
HEX (Hexadecimal)
A 6-digit (or 3-digit) base-16 number used heavily in HTML and CSS. It combines Red, Green, and Blue values (00 to FF). Example: #FF0000 is pure red.
RGB (Red, Green, Blue)
The standard color model for digital screens. Each color channel is represented by an integer from 0 to 255. Example: rgb(0, 255, 0) is pure green.
HSL (Hue, Saturation, Lightness)
A human-friendly representation of RGB. Hue is a degree on the color wheel (0-360), while Saturation and Lightness are percentages. Often preferred by designers for building accessible color palettes.
CMYK (Cyan, Magenta, Yellow, Key/Black)
A subtractive color model used primarily for physical printing (ink). While screens emit light (RGB), printed materials absorb light (CMYK).
Understanding Color Formats (HEX, RGB, HSL)
Web designers use multiple color formats. HEX is standard for CSS, RGB is ideal for screens and digital displays, and HSL (Hue, Saturation, Lightness) is preferred by designers for creating intuitive color palettes by easily adjusting brightness or saturation.
Frequently Asked Questions
What's the difference between RGB and HSL color models?
RGB defines a color by its red, green, and blue light intensities, which is how screens render colors. HSL (Hue, Saturation, Lightness) is more intuitive for humans to reason about — for example, increasing lightness always makes a color brighter without changing its hue.
Why do I need CMYK if I already have RGB or HEX?
CMYK (Cyan, Magenta, Yellow, Key/black) is a subtractive color model used for print production. RGB/HEX values are for screens; converting to CMYK is necessary when preparing designs for professional printing, though exact print results also depend on the printer's color profile.
What does a HEX code like #4F46E5 actually represent?
Each pair of hex digits (00–FF) represents the intensity of red, green, and blue respectively — so #4F46E5 breaks down to R=79, G=70, B=229, giving a vivid indigo/blue tone.
Is this tool accurate for design and development work?
Yes — all conversions use standard, well-documented color-space formulas, and the tool runs the same math your browser and design software use internally, so values match what you'd get in tools like Figma or Photoshop.
