Color Code Formats Explained
HEX (#RRGGBB): The most common format in web development. A 6-character code representing red, green, and blue channels in hexadecimal (0-255 → 00-FF). Example: #0F766E. Short form #RGB exists for colors where each channel's two digits are identical (e.g., #FF6600 → #F60). HEX is supported in all CSS contexts and design tools.
RGB (rgb(R, G, B)): Red, green, blue values as integers from 0 to 255. Example: rgb(15, 118, 110). Also supports alpha transparency: rgba(15, 118, 110, 0.5) for 50% opacity. More intuitive for mixing colors mathematically.
HSL (hsl(H, S%, L%)): Hue (0-360°), Saturation (0-100%), Lightness (0-100%). Example: hsl(176, 78%, 26%). HSL is the most human-intuitive format — "this color but 20% lighter" or "same hue but less saturated" are easy to express. Essential for creating consistent color variations in design systems.
Color Theory Basics for Non-Designers
The Color Wheel: Colors opposite each other on the color wheel are complementary — they create high contrast and visual tension. Colors adjacent on the wheel are analogous — they create harmony and flow.
Hue, Saturation, Lightness: Hue is the "what color" (red, blue, green, etc.). Saturation is how vivid vs. gray it is. Lightness is how bright vs. dark. Understanding these three axes lets you make controlled color modifications — darken a button on hover, create a muted background version of your brand color, or generate a full palette from a single hue.
Tints, Shades, and Tones: A tint is a color mixed with white (increasing lightness). A shade is a color mixed with black (decreasing lightness). A tone is a color mixed with gray (decreasing saturation). Most design systems generate a full scale (50-900 or 100-900) of tints and shades from each base color.
Building Color Palettes for Web Projects
A complete web color system typically needs:
- Primary color: Main brand color used for CTAs, active states, links, key UI elements. Needs 5-9 shade variations (100 through 900).
- Neutral/Gray scale: For text, backgrounds, borders, dividers. 9-10 shades from near-white to near-black.
- Semantic colors: Success (green), warning (yellow/orange), error (red), info (blue). Each with at least 3-4 variations for backgrounds, borders, and text.
- Accent color: Optional secondary color for visual variety and emphasis.
Starting from a single brand HEX code, you can use the HSL format to generate a full scale: same H and S, systematically varied L from 95% (lightest background) to 20% (darkest text).
Accessibility and Color Contrast
WCAG (Web Content Accessibility Guidelines) requires a minimum contrast ratio of 4.5:1 between text and background for normal text (AA compliance), and 3:1 for large text and UI components. Approximately 8% of men have some form of color vision deficiency — the most common being red-green color blindness.
When picking colors for web content:
- Always check contrast ratio between text color and background (tools like WebAIM Contrast Checker are free)
- Don't rely on color alone to convey information — add icons, patterns, or text labels
- Avoid red/green combinations as sole differentiators for important UI states
- Very light grays on white and very dark grays on dark backgrounds often fail contrast checks despite seeming acceptable
