Frequently Asked Questions
How do I create a CSS gradient?
Use our tool to select colors, adjust the angle, and set color stops. The CSS code is generated automatically in real time, and you can copy it with a single click to paste it directly into your stylesheet.
What is WCAG contrast and why does it matter?
WCAG (Web Content Accessibility Guidelines) defines contrast standards to ensure text is readable for everyone, including people with visual impairments. Level AA requires a ratio of 4.5:1 for normal text and 3:1 for large text. Level AAA requires 7:1 and 4.5:1 respectively.
How do I convert a HEX color to RGB?
A HEX color like #FF5733 is converted to RGB by separating the hexadecimal pairs: FF=255, 57=87, 33=51, resulting in rgb(255, 87, 51). Our tool does this automatically between HEX, RGB, HSL, HSB, and CMYK.
What color formats does this tool support?
We support HEX, RGB, RGBA, HSL, HSLA, HSB/HSV, and CMYK. You can convert between any format instantly and copy the result with a click.
Can I generate harmonious color palettes?
Yes! Our tool generates palettes based on color theory: analogous, complementary, triadic, and split-complementary schemes. You can also generate random palettes and lock individual colors while regenerating the rest.
Do I need to install anything to use these tools?
No, all tools work directly in your browser. You don't need to install extensions, plugins, or additional software. All processing is done on your device (client-side), without sending data to any server.
