🎨 Need AI-generated app icons with custom colors?
WhixFrame generates unique app icons in 6 styles — with your brand colors.
What This Tool Does
This generator produces harmonious 5-color palettes for a mobile app, then previews them live on a sample dashboard UI so you can judge how they actually look on buttons, cards, and text, not just as flat swatches. It checks each color's contrast ratio against white and black text so you can catch accessibility problems before they reach production.
It is built for developers and solo founders who need a workable palette fast, not a full brand identity system. It won't give you a rationale for why a color fits your brand positioning, and it won't generate a complete design system with spacing and elevation tokens. For a color scheme that looks intentional and passes basic contrast checks, it gets you there in seconds.

Click generate to get a 5-color harmonious set, or start from one of the quick presets.
Lock the colors you like
Click the lock icon on any color to keep it fixed while you regenerate the rest.
Check contrast
Each color shows its contrast ratio against white and black text, so you can spot accessibility issues immediately.
Preview and export
See the palette applied to a sample app UI, then export as CSS variables to drop into your project.
Frequently Asked Questions
Does this check color contrast for accessibility?+
Yes, the generator flags contrast ratios that fall below WCAG AA guidelines (4.5:1) for both white and black text against each color.
Can I export the palette for iOS and Android code?+
You can export the generated palette as CSS variables directly from the tool. Swift Color extensions and Kotlin/Compose definitions follow the same hex values, just written in your platform's syntax.
How do I lock a color I want to keep?+
Hover over any color block and click the lock icon. Locked colors stay fixed the next time you generate.
What if none of the presets fit my brand?+
Use the presets as a starting point, lock the one color closest to your brand, then regenerate to build the rest of the palette around it.
Is 5 colors enough for a full app?+
It covers the core roles most apps need: a dark base, a mid-tone surface, an accent, a secondary accent, and a light tone for text or backgrounds. Larger design systems can extend from these five.
Is this tool really free with no signup?+
Yes. Generation, locking, contrast checking, and CSS export are all free with no account required.
Common Mistakes
Ignoring contrast ratios
A palette that looks good as flat swatches can fail badly once real text sits on top of it. Check the W and B contrast badges before committing to a color for text or buttons.
Using too many accent colors
Five colors is already a lot if all of them compete for attention. Pick one primary accent and let the rest play supporting roles.
Choosing colors that all sit at the same lightness
A palette needs a range from dark to light to create visual hierarchy. If every color regenerates at a similar brightness, lock the darkest and lightest first, then regenerate the middle three.
Skipping a dark mode check
A palette that reads well on a light background can look muddy inverted. Preview both light and dark contexts before finalizing.
