概览

AI 生成的概览

本地 MCP 服务器，让助手模拟色盲视觉、重着色图像、检查配色安全性并生成石原氏色盲测试图。

可以做什么
  • 模拟颜色或图像在红色型、绿色型或蓝色型色觉下的呈现效果
  • 对图像重新着色，展示色盲视角
  • 用 CIEDE2000 色差判断配色是否仍可区分
  • 生成石原氏风格测试图并给出色盲友好的配色建议
适用场景
适合设计图表、配色、地图或界面并需保证色盲用户可读时使用，也适合预览图像在色盲者眼中的样子，或制作石原氏风格测试图。
运行要求
以本地 stdio 进程运行，从 npm 包 colorblind-mcp 安装，需要 Node.js。未声明账号、API 密钥或环境变量。
安装前请注意
README 称处理全部在设备本地完成、图像不会上传，但这只是提供方说法，清单本身无法验证。屏幕上的视觉测试明确不能作为诊断，结果受显示器校准、环境光和观看距离影响。

安装

在 SourceWeft 中

  1. 打开 控制台中的 Colorblind，将其添加到工作区。
  2. 为需要使用其工具的对话启用该服务。

Desktop only，通过 STDIO。 STDIO 服务会启动本地进程，因此需要 SourceWeft 桌面宿主。

其他 MCP 客户端

参照 仓库 中的启动说明。

An open, published method for color vision — and 17 vision tests built on it. Everything runs on the device. No account, no upload, no image ever sent anywhere.

The colorimetry is not a private formula: it is Machado, Oliveira & Fernandes (2009) deficiency simulation with CIEDE2000 color difference, published open access at doi.org/10.5281/zenodo.21310578, and shipped as packages so you can run the math yourself and check our numbers against yours.

Use the engine

bash
pip install cvdsafe          # is this palette colorblind-safe?npm  install cvdsafe
python
import cvdsafecvdsafe.is_safe(["#d7191c", "#1a9641"])   # False — red and green collapse under deutan
bash
npx cvdsafe "#d7191c" "#1a9641"           # exits 2 if the palette is unsafe — CI-friendly
what you wantpackage
Is this palette safe?cvdsafe · npm + PyPI, with a CLI
Show me how it lookscvdsim — recolors an image for protan/deutan/tritan
Give me safe colorssafepalette — Okabe–Ito, extended and verified
For matplotlibcvdmaps — set_cycle() and you're safe
Make test platescvdplate · ishihara
Acuity mathlogmar — logMAR ↔ Snellen ↔ decimal
One deficiencyprotan · deutan · tritanopia · dichromacy · achromatopsia · trichromacy

For LLM tools: cvdsafe-mcp and colorblind-mcp are MCP servers, listed in the official Model Context Protocol registry — so an assistant can check a palette or generate an Ishihara plate as a native tool.

The tests

Color vision, D-15 arrangement, hue discrimination, anomaloscope-style matching, contrast sensitivity, acuity, astigmatism, Amsler grid, blind spot, vernier alignment, flicker fusion, saturation, dominance, reaction, stereo depth, digital eye strain, and a shape-based test for kids.

A test on a web page cannot be a diagnosis: an uncalibrated display, ambient light and viewing distance all move the result. Each test says so where it reports, and points at an eye examination rather than standing in for one.

Audit it yourself. opticquiz.com/methodology answers the eight questions worth asking of any online vision test — who made it, what it measures, what it assumes about your screen, whether it has been clinically validated (it has not), what it cannot measure, and who pays for it.
