This color shade generator creates a range of progressively darker versions of any base color by mixing in black at configurable steps, giving you a ready-made scale for hover states, borders, and depth in a UI. It's a practical tool for designers building consistent dark variants for buttons and components, and for developers who need a quick set of darker CSS values without manually calculating each one. Enter a base color and set how many steps you want, and the generator produces each shade with its hex code and a live swatch, evenly stepping the darkness from your original color toward black. The tool runs entirely in your browser, so your palette work is never uploaded or shared with a server. Shades are generated using precise lightness reduction in the HSL color space, keeping hue and saturation consistent so the darkened colors still clearly relate to your original. Enter your base color below to generate a shade scale.

Frequently asked questions
What is a 'shade' in color theory?
A shade is a color mixed with black, which reduces its lightness while keeping the same hue - useful for hover, active, or pressed states in UI design.
How many shade steps should I generate?
5 to 9 steps typically gives enough range for common UI needs like default, hover, and active states without an unmanageable number of variants.
What's the difference between a shade and a tint?
A shade darkens a color by mixing in black, while a tint lightens it by mixing in white - they move in opposite directions from the base color.
Does darkening a color change its hue?
No, this tool reduces only the lightness value in HSL space, keeping the hue fixed so all shades clearly belong to the same color family.
Can I use generated shades for dark mode UI?
Yes, shade scales are commonly used to build dark-mode-appropriate variants of brand and accent colors.
Should I check contrast for generated shades used as text?
Yes, always verify contrast ratio against your background using a WCAG contrast checker before using any generated shade for text.
