Common HSL to HEX Conversions

Primary Hues

  • hsl(0, 100%, 50%) → #FF0000
  • hsl(120, 100%, 50%) → #00FF00
  • hsl(240, 100%, 50%) → #0000FF

Saturation & Lightness

  • hsl(0, 100%, 75%) → #FFA6A6
  • hsl(0, 100%, 25%) → #800000
  • hsl(0, 50%, 50%) → #BF4040

Understanding the HSL Color Model

The HSL color model is more intuitive than RGB or HEX for many designers:

Hue (0-360°)

The color type (red, green, blue, etc.) represented as a position on the color wheel.

Saturation (0-100%)

The intensity or purity of the color. 0% is grayscale, 100% is the full color.

Lightness (0-100%)

How light or dark the color is. 0% is black, 100% is white, 50% is the normal color.

Practical Uses in CSS

Converting HSL to HEX is useful for CSS development, especially when working with design systems:

:root {
  /* Primary color with variations */
  --primary-hue: 210; /* Blue */
  --primary: #0C71D1;         /* hsl(210, 90%, 43%) */
  --primary-light: #63A9E8;   /* hsl(210, 90%, 65%) */
  --primary-dark: #064883;    /* hsl(210, 90%, 25%) */
  
  /* Secondary color with variations */
  --secondary-hue: 25; /* Orange */
  --secondary: #F28C28;       /* hsl(25, 90%, 55%) */
  --secondary-light: #FFB673; /* hsl(25, 90%, 73%) */
  --secondary-dark: #B15600;  /* hsl(25, 90%, 33%) */
}

/* Usage */
.button {
  background-color: var(--primary);
  border: 2px solid var(--primary-dark);
}

JavaScript Implementation

Convert HSL to HEX programmatically with this JavaScript function:

// Complete HSL to HEX converter function
function hslToHex(h, s, l) {
  // Convert HSL percentages to decimal
  s /= 100;
  l /= 100;

  // Calculate RGB values
  const c = (1 - Math.abs(2 * l - 1)) * s;
  const x = c * (1 - Math.abs((h / 60) % 2 - 1));
  const m = l - c/2;
  
  let r, g, b;
  
  if (h >= 0 && h < 60) {
    [r, g, b] = [c, x, 0];
  } else if (h >= 60 && h < 120) {
    [r, g, b] = [x, c, 0];
  } else if (h >= 120 && h < 180) {
    [r, g, b] = [0, c, x];
  } else if (h >= 180 && h < 240) {
    [r, g, b] = [0, x, c];
  } else if (h >= 240 && h < 300) {
    [r, g, b] = [x, 0, c];
  } else {
    [r, g, b] = [c, 0, x];
  }
  
  // Convert to 0-255 range and then to HEX
  const toHex = (value) => {
    const hex = Math.round((value + m) * 255).toString(16);
    return hex.length === 1 ? '0' + hex : hex;
  };
  
  return '#' + toHex(r) + toHex(g) + toHex(b);
}

Frequently Asked Questions About HSL to HEX Conversion

Why use HSL instead of direct HEX values?

HSL (Hue, Saturation, Lightness) is more intuitive for creating color schemes and adjusting colors. It's easier to create harmonious variations by simply adjusting saturation or lightness while keeping the same hue. Once you've found the perfect color in HSL, converting to HEX makes it compatible with all CSS contexts and color requirements.

How does HSL compare to other color models?

Compared to other color models:

  • RGB/HEX: More technical, less intuitive for design adjustments
  • HSL: Intuitive for creating color variations and schemes
  • HSV/HSB: Similar to HSL but with brightness instead of lightness
  • CMYK: Print-focused, not ideal for web design

Can HSL represent all colors that HEX can?

Yes, both the HSL and HEX color models can represent the same range of colors in the sRGB color space, which is the standard for web design. However, neither can represent colors outside the sRGB gamut. The HSL model simply provides a more intuitive way to think about and manipulate these colors.
