Terms & Conditions

2. Description of the Service

PigmentLab offers online computational color science tools, including:

• Subtractive Color Mixing Studio: Kubelka-Munk optical absorption and scattering simulations.
• Bauhaus Artist Wheel: Johannes Itten 12-hue RYB circle with classical harmony and shade generators.
• Accessibility Auditing: WCAG 2.1 contrast ratio calculations and Daltonization CVD simulation previewers.
• CSS & Design Token Exporters: Real-time CSS color-mix(), OKLCH, OKLab, HEX, RGB values.

We reserve the right to improve, modify, or temporarily suspend aspects of the service without prior notice to maintain software quality.

3. Ownership of Generated Colors & Commercial License

We believe color is a universal human asset. PigmentLab claims zero ownership over any color values, color palettes, mix recipes, or CSS styling code generated using our platform.

You are granted a worldwide, perpetual, irrevocable, royalty-free license to use, publish, distribute, incorporate, and commercially exploit any color combinations, palettes, or CSS code you produce using PigmentLab in:

• Commercial web and mobile software, UI kits, design systems, and apps.
• Physical artworks, paintings, textiles, interior design, and industrial products.
• Marketing collateral, branding assets, logo design, and printed media.
• Open-source software libraries and educational curriculum materials.

4. Intellectual Property of PigmentLab

While your generated color outputs belong entirely to you, the PigmentLab website, its visual interface, brand identity, logos, proprietary mathematical source code, and original instructional documentation are the intellectual property of PigmentLab and are protected under international copyright and trademark laws. You agree not to reverse-engineer, decompile, or frame the website for competitive replication without express prior written consent.

5. Color Accuracy & Scientific Disclaimer

PigmentLab strives for the highest degree of physical and optical realism. However, please be advised of inherent physical and display limitations:

• Display Hardware Gamuts: Consumer displays operate in RGB color gamuts (sRGB, Display P3). Certain physical paint pigments possess reflectance spectra that lie outside standard digital gamut boundaries.
• Manufacturer Variations: Real-world paint formulations (e.g., Cadmium Yellow or Cobalt Blue) vary between brands (Winsor & Newton, Golden, Gamblin) based on pigment binder purity, mill grain size, and optical density.
• Industrial Applications: For critical industrial manufacturing (automotive coatings, commercial plastics, textile batch dyeing), computational models must always be physically validated using spectrophotometers in a controlled lighting booth.

6. Acceptable Use Policy

When using PigmentLab, you agree not to:

• Attempt to disrupt, flood, or compromise our hosting network through denial-of-service (DDoS) attacks.
• Deploy automated scrapers or bots in a manner that degrades service performance for other creators.
• Misrepresent PigmentLab or falsely claim official endorsement by PigmentLab.

7. Disclaimer of Warranties

PigmentLab is provided on an "as is" and "as available" basis, without warranties of any kind, whether express, statutory, or implied. To the fullest extent permissible by law, PigmentLab disclaims all warranties, including merchantability, fitness for a specific purpose, accuracy, or uninterrupted service.

8. Limitation of Liability

Under no circumstances shall PigmentLab, its founders, or contributors be held liable for any direct, indirect, incidental, special, or consequential damages (including loss of profits, physical dye production errors, or business interruption) resulting from the use or inability to use the platform.

9. Governing Law

These Terms shall be interpreted and governed in accordance with applicable general commercial laws, without regard to conflict of law principles.
