概覽

AI 產生的概覽

本機 MCP 伺服器，讓助理模擬色盲視覺、重新上色影像、檢查配色安全性並產生石原氏色盲測試圖。

可以做什麼
  • 模擬顏色或影像在紅色型、綠色型或藍色型色覺下的呈現結果
  • 重新上色影像，呈現色盲者看到的樣子
  • 以 CIEDE2000 色差判斷配色是否仍可分辨
  • 產生石原氏風格測試圖並提供色盲友善的配色建議
適用情境
適合設計圖表、配色、地圖或介面且需確保色盲使用者可讀時使用，也適合預覽影像在色盲者眼中的樣貌，或製作石原氏風格測試圖。
執行需求
以本機 stdio 程序執行，從 npm 套件 colorblind-mcp 安裝，需要 Node.js。未宣告帳號、API 金鑰或環境變數。
安裝前請注意
README 表示處理全在本機完成、影像不會上傳，但這只是提供方的說法，清單本身無法驗證。螢幕上的視覺測試明確不能作為診斷，結果受螢幕校正、環境光與觀看距離影響。

安裝

在 SourceWeft 中

  1. 開啟 儀表板中的 Colorblind，將其新增到工作區。
  2. 為需要使用其工具的對話啟用該服務。

Desktop only，透過 STDIO。 STDIO 服務會啟動本機處理程序，因此需要 SourceWeft 桌面主機。

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

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.
