DIGITAL
Inspect and test screen color.
Find colors, sample images, calculate WCAG contrast, build gradients, and inspect the color system used by a public website.
ABOUT HEXCHECK
One color can lead to a lot of real decisions.
HexCheck is a connected color platform for digital products, design systems, homes, beauty, and fashion. Start with the information you already have, then move into the tool that answers the next question without rebuilding the work from scratch.

THE PLATFORM TODAY
A color platform, not one calculator.
HexCheck now covers the technical side of color and the real situations where color decisions get made. Each area uses focused tools rather than forcing every question into the same interface.
02
DESIGN
Turn colors into reusable systems.
Build coordinated palettes, document full brand systems, browse curated references, and learn practical color workflows.
03
HOME
Apply color to rooms and materials.
Compare paint-ready references, simulate lighting changes, assign room surfaces, and coordinate paint with wood, stone, metal, and textiles.
04
BEAUTY
Compare complexion and cosmetic color.
Explore undertone direction, narrow foundation families, evaluate lip colors, and compare seasonal temperature, contrast, and chroma.
05
FASHION
Coordinate a complete look.
Build role-based outfit palettes, extract colors from fabrics, compare metals and stones, and choose finishing accessory colors.
THE CONNECTED IDEA
Start with what you know. Keep the useful context.
A hex value, image, website, fabric, complexion sample, room color, or existing item can become the starting point. HexCheck is designed to keep that context available as the question changes.

4PreserveSave the work, document the system, or export the result.
One color can move through the platform.
The global color switcher and tool handoffs let supported workflows reuse the current color or complete color set.
Tools are designed to continue each other.
Contrast results, palette colors, scanner findings, and applied color choices can open the next relevant workspace with less repeated setup.
Important work can survive the session.
Pro workspaces preserve saved colors, comparisons, palettes, gradients, collections, brand systems, scanner reports, and history.
MEET PALETTE
A color companion inside HexCheck.
Palette is designed to feel more like a helpful desktop companion than a generic support chat. She can answer color questions, remember the working set, understand conversational follow-ups, and point to the right HexCheck tool.
- Deterministic color skillsCore calculations and common color questions are handled locally and consistently.
- Conversation memoryPalette can follow references such as “the second one,” remember rejected colors, and continue an unfinished decision.
- Tool awarenessShe can explain HexCheck, open the relevant workspace, and carry supported colors into it.
- Plan-aware guidancePalette can explain paid features without exposing output that belongs inside a Pro workflow.

A ONE-PERSON PROJECT
Built after hours, one careful improvement at a time.
HexCheck is designed, written, tested, and maintained by one person in spare time. It began as a practical way to learn more deeply about color, accessibility, product design, and software development. It has grown into a passion project with a much larger platform than originally planned.
Using the tools, sharing thoughtful feedback, reporting bugs, and telling someone about HexCheck all help it continue. Voluntary support helps cover the services and time required to keep improving the project, but it is never required to use the free tools.
HONEST LIMITS
Color tools are most useful when their limits are visible.
HexCheck provides calculations, comparisons, structured references, and practical starting points. The final decision still belongs in the real environment where the color will be used.
Screens, cameras, lighting, finishes, materials, and surrounding colors can change how the same value appears.
WCAG ratios are measurable, but accessible implementation also depends on type size, states, semantics, content, and interaction.
Home, Beauty, and Fashion tools compare color direction and relationships. They cannot promise an exact physical, cosmetic, or material match.
The scanner can inventory accessible HTML and linked CSS. Colors created only after JavaScript runs may not be detected.
Features, integrations, outputs, limits, and availability may change as reliability and the connected workflow improve.
START WITH WHAT YOU HAVE
A color, a photo, a room, a product, or an idea.
Choose the area that matches the decision, and HexCheck will help move the color forward.
