Greyscale Desaturate Color
Convert any hex to grayscale color instantly. Desaturate color with full color desaturation—copy grayscale hex codes as HEX, RGB, or HSL.
Tool powered by ccolor on fffuel.
Convert hex to HSL, RGB, and HSB. Get clear hex codes and transparent color values with fffuel CCColor—copy CSS-ready color codes instantly.
Hex to HSL and RGB: Convert in either direction—paste HEX or adjust HSL sliders and copy the values your CSS file needs.
Clear and transparent HEX: Work with 8-digit hex (#RRGGBBAA) so transparent color codes match overlays and glass UI.
Hue–saturation picker: Use the wheel as a hue saturation color picker, then refine lightness without leaving the tool.
Tint, shade, and tone ramps: Generate related swatches from a base color instead of hand-building a rrggbb-style chart elsewhere.
One-click copy: Copy HEX, HSL, RGB, or OKLCH when the upstream UI exposes them—ready for HTML and CSS.
Browser-only: Picking and conversion run client-side through the fffuel tool; This site does not store your colors.
Open the tool
Use the frame below after this guide. If it does not load, open fffuel CCColor in a new tab from the FAQ link.
Paste or pick a color
Enter HEX, rgb(), or hsl(), or drag on the hue–saturation area to set a new base color.
Set transparency if needed
Lower alpha when you need a clear hex code or transparent color code for overlays.
Read HSL and RGB
Copy hex to HSL (or HSB-style values when shown) for variables, Tailwind config, or design tokens.
Use palette chips
Pull tints, shades, or complements from the built-in ramps when building a small system.
Validate in context
Test the color on real backgrounds; for contrast, follow up with /color-contrast .
Prefer HSL for theme tweaks
After hex to HSL conversion, nudge lightness for hover states without shifting hue.
Name alpha in tokens
Document which background a transparent color code was tuned for so it is not reused on the wrong surface.
Use 8-digit HEX in design handoff
A clear hex code in #RRGGBBAA form travels cleanly between Figma plugins and CSS.
Check stacked transparency
Two translucent layers can look darker than either swatch alone—preview on the real layout.
Keep a solid reference
Store the opaque pair when you derive a transparent color code so rebrand updates stay traceable.
Front-end developers
Convert hex to HSL for custom properties, then paste transparent color codes for modals and scrims.
UI designers
Use the hue saturation color picker, then export HEX for Figma or code without manual math.
Design system owners
Document clear hex code rules and ramp tokens from one base color.
Marketing builders
Match landing page hex background values to component libraries quickly.
One place for fffuel tools
Open CCColor beside gradients and backgrounds that also expect precise HEX input.
Faster format switching
Stop retyping when you need hex to HSL for CSS but HEX for a design export.
Transparent codes without guesswork
See alpha in the picker instead of trial-and-error in DevTools.
