Color Converter

Designers usually live in a world of HEX codes (like #FF0000). But when developers try to add dynamic opacity or hover effects to a button in CSS, HEX codes become incredibly difficult to manipulate.

Converting that static HEX code into an RGB or HSL format allows developers to surgically target the 'alpha' channel. You can take a designer's exact brand color and instantly make it 50% transparent without having to open Photoshop.

Most developers agree that HSL (Hue, Saturation, Lightness) is the superior color format for modern UI design. Unlike HEX, which looks like random computer gibberish, HSL is intuitive.

If you have a primary blue button and you want a darker blue for the hover state, guessing the right HEX code is impossible. But with HSL, you can literally just decrease the 'Lightness' percentage by 10%. This converter bridges the gap between those legacy formats and modern development practices.

HEX, RGB and HSL describe the same colours in different ways. #FF5733 in HEX equals rgb(255, 87, 51): FF is 255 red, 57 is 87 green and 33 is 51 blue. HSL describes hue, saturation and lightness, which makes it easier to create lighter or darker shades by changing a single number.

Pretty colours can be hard to read. The Web Content Accessibility Guidelines recommend a contrast ratio of at least 4.5:1 between normal text and its background, and 3:1 for large text. Test your final combination with a contrast checker. If you are tidying a stylesheet, minify it with the CSS Minifier after converting colours.
