What color models does this MCP support?

The MCP supports CIE76, CIEDE2000, and OKLAB models for calculating color differences.

How do I use this with Claude?

You connect to the MCP through the Vinkius platform. Once connected, your Claude client can call the capabilities directly.

Can I use this to find the closest color in a list?

Yes, you can use the rank_colors_by_similarity capability to sort a list of colors based on their distance from a target.

What is the difference between Hex and perceptual distance?

Hex is a digital representation of color, while perceptual distance measures how different two colors actually look to a human being.

Do I need to host this myself?

No, Vinkius hosts and manages the MCP for you, so it is ready to use immediately after connection.

What color models are supported?

The engine supports CIE76, CIEDE2000, and OKLAB for calculating perceptual distance.

How do I use the ranking capability?

Use rank_colors_by_similarity by providing a target Hex color and an array of candidate Hex strings.

Can I check if two colors are within a specific tolerance?

Yes, the evaluate_proximity capability allows you to define a threshold value to see if the difference is small enough.

Works with modern AI clients that support MCP, including ChatGPT, Claude, Cursor, and more.

Your AI does the work. We keep it safe and sound.

No other AI tool gives you this. Your workflow runs in the client you already love, your account stays protected, and you decide what the agent can and cannot do. It is the whole reason to make the switch.

Each Connector lives inside our infrastructure, the same place where your workflow runs. The three things below are already part of it, working quietly in the background so you never have to think about them. Nothing to add, nothing to set up, nothing to worry about.

V8 Isolate01

Each Connector runs inside its own sealed environment.

Each Connector runs inside its own sealed V8 runtime — no access to your files, your system, or other servers. A Connector never sees past its own request.

Kill Switch02

One switch stops every agent. Instantly.

One action deactivates every Connector, revokes every token, and ends every session at once. AI Governance keeps the record.

FinOps per User03

Spending limits that pause instead of surprise.

Every user keeps their own connections and credentials, isolated from everyone else. Anything that would cross your spending limit is held for your approval, not billed.

Three controls, built into the layer your AI connects through.

Capability set01 / 01

01-04

4 capabilities in this set.

Part of 4 available through Color Difference Engine.

01
Evaluate proximity
This capability checks if two colors are close enough based on a margin of error you define. It's useful for automated tolerance testing.
02
Get color components
This capability breaks a single color down into its lightness, chroma, and hue dimensions. It helps you understand the specific properties of a color.
03
Rank colors by similarity
This capability sorts a list of candidate colors from most similar to least similar compared to a target. It's perfect for finding the best match in a large set.
04
Calculate color difference
This capability calculates the perceptual distance between two Hex colors. It supports CIE76, CIEDE2000, and OKLAB models.

Real work

What teams actually run

Brand Compliance

Check if a newly generated UI color is within a specific Delta E distance from a brand's primary color.

Palette Generation

Find the most similar colors in a library to create harmonious color schemes.

Accessibility Audits

Use color component data to check if lightness levels meet contrast requirements.

Automated Testing

Run scripts to ensure color values in code haven't drifted from the original design intent.

One connector, every AI

Color Difference Engine works with the most popular AI clients.

These are the most popular clients, each with a step-by-step guide: one link, set up once, with governance and visibility built in. And because everything runs on the MCP standard, the same connection also works in any other compatible client — nothing to rebuild.

Building your own app? The connector is yours to use.

You don't need a client to put Color Difference Engine to work: the same hosted connection plugs into your own applications and agent code, with the same governance on every request. Build with it, chat with it — one connection for both.

Preview access · not provider authentication

The vk_preview_* token belongs to Vinkius preview infrastructure. It lets Claude discover and display the capabilities of Color Difference Engine, so you can see the experience inside your AI.

It does not authenticate your account with Color Difference Engine. Actions requiring credentials or live account data may not run until you activate the Connector and authorize the service.
