What is a Color Code Converter?

A color code converter translates colours between different notation systems used in web development and design: HEX (#ff5733), RGB (rgb(255,87,51)), HSL (hsl(11,100%,60%)), RGBA, and HSV. Each format represents the same colour differently — HEX and RGB for web/CSS, HSL for human-intuitive adjustments.

Why Use This Tool

Design tools, CSS, and APIs use different color formats. Figma might output HSL while your CSS uses HEX. A converter ensures consistent colors across your entire workflow without manual calculation.

When to Use It

Use color conversion when transferring colors from design tools to code, creating hover/active state variants by adjusting HSL lightness, debugging unexpected color rendering, or ensuring brand color consistency.

Common Uses

  • Converting design tool colours (Figma outputs HSL, CSS uses HEX)
  • Adjusting colour lightness/saturation in HSL format
  • Converting brand colours between formats for consistency
  • Debugging CSS colour values that aren't rendering as expected

Frequently Asked Questions

What is the difference between RGB and HSL?

RGB (Red, Green, Blue) defines colour by mixing light primaries. HSL (Hue, Saturation, Lightness) is more intuitive for humans — hue is the colour type (0–360°), saturation is intensity, lightness is brightness. HSL makes it easy to create colour variants (e.g., change only lightness for hover states).

What does the alpha channel mean in RGBA/HSLA?

Alpha represents opacity from 0 (fully transparent) to 1 (fully opaque). rgba(255,0,0,0.5) is a 50 % transparent red.

How do I convert a HEX colour to RGB?

Split the 6-digit hex into 3 pairs (RR, GG, BB) and convert each from hexadecimal to decimal. For example, #FF5733 → R=255, G=87, B=51 → rgb(255, 87, 51). CipherKit does this conversion instantly.
