Colors
Generator für UI-Button-Farben
Used by developers, writers, and creators worldwide.
A UI button color generator builds a coordinated set of button colors from a single primary hue so every button variant in your interface stays visually unified. It returns a saturated primary fill, a contrast-checked text color computed from the real relative luminance of that fill, a soft secondary fill with its own readable text, an outline border tone for ghost buttons, and a complementary accent for calls to action that need to stand apart. Because the text color is chosen by comparing actual WCAG contrast against white versus near-black, your primary buttons stay legible without manual checking. Designers and developers use it to seed a button component library, define primary and secondary token pairs, or quickly mock a button hierarchy. Each value is a labelled, paste-ready hex code that maps directly onto background, color, and border declarations in your stylesheet or design system.

FAQ
how is the button text color chosen
It computes the relative luminance of the primary fill using the WCAG sRGB formula and compares the contrast of white versus near-black text on it, returning whichever reaches the higher ratio so the label stays readable.
what is the secondary button for
The secondary fill is a soft, low-saturation tint of your hue for lower-priority actions. Pairing a bold primary with a quiet secondary creates a clear hierarchy so users know which action is the main one.
can i use these as design tokens
Yes. Each labelled hex maps cleanly onto tokens like button-primary, button-primary-text, and button-secondary, so you can drop them straight into a design system or CSS custom properties.
