ChromaCraft

ChromaCraft is a powerful, offline-first color palette studio and accessibility explorer designed for designers, developers, and digital creators. Generate harmonious color schemes, fine-tune tones with a precision HSV color wheel, test color combinations against real-world UI mockups, and simulate color blindness in real time—all with zero account requirements and zero data collection. REAL-TIME LIVE UI PREVIEW Test how your colors look in practice before writing a single line of code: • Mobile App Mockup: See your palette applied to app bars, gradient hero banners, metric cards, action buttons, and navigation. • Dashboard & Data Visualization: Verify color contrast across interactive bar charts and progress ring graphs. • Typography & Readability Matrix: Test pairwise text contrast with instant WCAG 2.1 ratings. • E-Commerce Card: Preview surface colors, product badges, price tags, and call-to-action buttons. COLOR VISION DEFICIENCY SIMULATOR Ensure your digital products are accessible to everyone: • Optical LMS Cone Simulations: Real-time simulation of Deuteranopia (green deficiency), Protanopia (red deficiency), Tritanopia (blue-yellow deficiency), and Achromatopsia (monochromacy). • Distinction & Conflict Detector: Automatically detects and warns when two colors become difficult to distinguish under color deficiency. • Pairwise WCAG 2.1 Contrast Checker: Immediate pass/fail scoring for AAA, AA, and AA Large standards. PRECISION COLOR WHEEL & FINE ADJUSTMENT • 2D Polar Hue-Saturation Wheel: Intuitive touch-drag selector for seamless hue (0–360°) and saturation (0–100%) navigation. • Precision Sliders: Fine-tune Hue, Saturation, and Brightness/Value with exact numerical readouts. • Shade & Tint Ladder: Automatically generates stepped lighter tints and darker shades for every hue. • Direct Hex Input: Type or paste hex codes with live validation and side-by-side comparison swatches. COLOR HARMONIES & STUDIO WORKFLOW • Harmonic Schemes: Instant generation using color theory principles, including Balanced, Complementary, Analogous, Triadic, Split-Complementary, Tetradic, and Monochromatic. • Individual Swatch Locking: Lock specific favorite colors while rolling and generating new companion shades. • Dual View Modes: Switch between a full-bleed vertical deck ribbon view and detailed telemetry cards with HSL and contrast ratios. • Undo & Redo History: Effortlessly step backward or forward through your palette edits. 100% OFFLINE & PRIVACY-FIRST • No Account Required: Start creating immediately without sign-up forms, logins, or cloud dependencies. • Local Storage: All saved palettes and tags are stored strictly on your device using Android Room. • Zero Data Collection: No tracking, no behavioral analytics, and no advertising SDKs. MULTI-FORMAT CODE EXPORT Export your palettes directly into your development workflow: • Jetpack Compose Kotlin color definitions • CSS Custom Properties / Variables (:root) • Android XML resource format () • Raw Hex code arrays and formatted text
