sRGB is the common web default; wide-gamut displays can show colors outside sRGB—browsers clamp unless you use newer color functions.

Color spaces express the same hue with different numeric encodings—HEX is compact; RGB is device channels; HSL is intuitive for lightness shifts. Use it when you are copying palette values between Figma, CSS, and Canvas. See also Contrast checker for a related utility in this cluster.
How to use this calculator
- Open the tool: Paste a HEX or rgb()/hsl() string.
- Tune inputs: Adjust sliders if you need small tweaks.
- Read the output: Copy the output format your codebase expects.
Real-world examples
- #3366CC: Expands to rgb(51, 102, 204)—verify contrast against your background separately.
- hsl(220,70%,50%): Easy to darken by lowering L—watch saturation on very dark backgrounds.
Tips & gotchas
Always run WCAG contrast checks—pretty blues often fail text contrast on white.
FAQ
Alpha channel?
If your tool supports rgba/hsla/8-digit HEX—preserve alpha when converting formats.
Does this tool send my text to a server?
Calciverse runs in your browser; we do not store your inputs on our servers for these utilities. Anything that uses network APIs (for example DNS lookup) only sends what you explicitly request.
Why do results differ from another site?
Rounding, defaults, and implementation details (color spaces, tokenizers, DNS resolvers) can differ. Compare definitions, not just the headline number.
