📖 This browser color tool fit convert color value, build palette, check contrast and help you inspect color details fast.
E support live bidirectional conversion between HEX, RGB, and HSL color formats. Enter any format to automatically sync updates across others, ensuring color consistency.
E fit build one-color family, opposite pair, near colors and triadic mixes by itself so your color combo go balance.
E check whether your text and background color meet WCAG 2.1 so more people fit read am well.
E give detailed color property analysis including relative luminance, perceived lightness, hue, saturation, and lightness to help understand color characteristics.
You fit copy HEX, RGB and HSL with one click. Each palette color sef fit copy one by one.
Perfectly adapts to different device screens including desktop, tablet, and mobile. Analyze colors anytime, anywhere without installing any software.
Color standards and calculation methods used by dis tool:
Technical Note:Dis tool uses JavaScript color algorithms for live conversion. Contrast calculation na based on WCAG 2.1 relative luminance formula: L = 0.2126×R + 0.7152×G + 0.0722×B. Palette generation na based on color wheel mathematical calculations: Complementary (180° hue difference), Analogous (30° hue difference), Triadic (120° hue difference).
WCAG (Web Content Accessibility Guidelines) na web content accessibility guidelines. Color contrast standards ensure sufficient contrast between text and background so visually impaired users fit read clearly. According to WCAG 2.1, normal text requires at least 4.5:1 contrast, large text (at least 18pt or 14pt bold) requires at least 3:1. Not meeting dese standards may make websites unusable for some users and could violate accessibility laws in some regions.
Each format has its characteristics:
1) HEX (Hexadecimal): e.g. #4A90E2, most commonly used in web development, concise but less intuitive for understanding color properties
2) RGB (Red Green Blue): e.g. rgb(74, 144, 226), based on light's primary colors, intuitive but less convenient for adjusting color characteristics
3) HSL (Hue Saturation Lightness): e.g. hsl(212, 72%, 59%), based on human color perception, easy to adjust color characteristics (like brightening, darkening, adjusting saturation)
ColorLab supports live conversion between dese three formats. You fit use whichever format na most convenient for your needs.
ColorLab generates four types of palettes based on color theory:
1) Monochromatic palette: Keeps hue constant, adjusts saturation and lightness to create lighter/darker variations
2) Complementary palette: Uses colors opposite on di color wheel (180° hue difference), creates high-contrast combinations
3) Analogous palette: Uses adjacent colors on di color wheel (30° hue difference), creates harmonious, subtle combinations
4) Triadic palette: Uses three equally spaced colors on di color wheel (120° hue difference), creates vibrant, colorful combinations
Dese palettes na mathematically calculated to ensure harmonious color combinations.
Relative luminance na a brightness value based on human visual perception, ranging from 0 (pure black) to 1 (pure white). Di calculation formula considers human eye sensitivity to different colors (most sensitive to green, least to blue). Perceived lightness na an intuitive description based on relative luminance classification, such as "very dark," "dark," "medium," "light," "very light." Relative luminance na used to calculate color contrast, while perceived lightness helps understand color visual weight and suitable applications.
Recommendations for choosing accessible colors:
1) Use ColorLab to check contrast, ensure text and background contrast ≥4.5:1
2) Avoid relying solely on color to convey information (e.g., red for errors), also use text or icons
3) Test from colorblind user perspectives, ensure color differentiation doesn't depend solely on hue differences
4) Provide sufficient color contrast to ensure clear identification even in bright environments
5) Consider color performance in dark mode, ensure good contrast across different themes
