🔰瀏覽器套件 ### ⚙️全網頁檢測- [WAVE檢測工具 <i class="fa fa-external-link"></i>](https://wave.webaim.org/extension/) (⭐檢視h1-h6巢狀結構方便找) > 可進行單頁線上檢測,或下載插件版使用。只要輸入要檢測的頁面網址,則會直接將該頁的檢測結果呈現於清單中,並列出不符合規範標準的各項內容。 [Web Developer檢測工具 <i class="fa fa-external-link"></i>](https://chrispederick.com/work/web-developer/) > 英文版的網頁插件,以瀏覽器擴充套件的方式安裝,安裝後可依照要檢視的項目選取該功能,如選擇檢視圖片、title屬性或其他各項網頁元素/標記,結果會顯示在網頁上,方便直接檢視。![](https://i.imgur.com/qHEMBrH.jpg) > ### ⚙️標題層級檢測- Heading map工具[Chrome <i class="fa fa-external-link"></i>](https://chrome.google.com/webstore/detail/headingsmap/flbjommegcjonpdmenkdiocclhjacmbi) [FireFox <i class="fa fa-external-link"></i>](https://addons.mozilla.org/zh-TW/firefox/addon/headingsmap/) > 執行後即在瀏覽器左側開啟視窗,以列表方式依序列出網頁的標題層級(headings),幫助使用者快速檢視標題層級的配置是否符合規範標準。(但不好用) ### 🎨顏色檢測- WCAG-Contrast-Checker色彩檢測工具 [Chrome <i class="fa fa-external-link"></i>](https://addons.mozilla.org/en-US/firefox/addon/wcag-contrast-checker/) [FireFox <i class="fa fa-external-link"></i>](https://chrome.google.com/webstore/detail/wcag-color-contrast-check/plnahcmalebffmaghcpcmpaciebdhgdf/related) > 用來檢查網頁文字及背景色彩的色彩對比值,並判斷是否符合規範標準。 > 可依據CSS樣式表指定的色彩自動比對,Chrome瀏覽器使用者則可使用滴管功能手動選取色彩進行比對。![](https://i.imgur.com/xB5V3Wx.jpg) ## 🔰軟體 ### 👁️色盲模擬器- [Color Oracle <i class="fa fa-external-link"></i>](https://colororacle.org/) > 非常好用的色盲模擬器,支持Mac / Win / Linux。大約8%的男人和0.5%的女人有色盲或色弱、是相當大的族群。當然,UI中不應該只通過顏色來區分信息,但有時無論如何會用到色彩區分(比如數據可視化),那麼就一定要使用色盲友善的配色方案。一般來講,藍/黃、藍/橙是比較萬用的搭配。 ### 🎨顏色檢測- ⭐[Colour Contrast Analyser (CCA) <i class="fa fa-external-link"></i>](https://www.tpgi.com/color-contrast-checker/) > 使用滴管功能選取網頁文字及背景色彩,即可立即換算出色彩對比值,並判斷是否符合規範標準。(吸色及色碼轉換方便) ![](https://i.imgur.com/rAkGfdI.jpg) ## 🔰UI軟體套件(Figma為主) [Stark(Figma, Sketch, Adobe XD)<i class="fa fa-external-link"></i>](https://www.getstark.co) > 在設計軟件裡選中兩個圖層就能計算出色彩對比度、告訴你是否負責無障礙標準。 > 不達標的時候,它還會推薦最接近當前顏色並且符合標準的色彩建議、一鍵替換,非常方便(一鍵替換這個功能只能免費用3次,之後需要付費訂閱)。![](https://i.imgur.com/I2g99Yn.jpg) [Figma: Find and Replace Colors <i class="fa fa-external-link"></i>](https://www.figma.com/community/plugin/806266638862897503/Find-and-Replace-Colors) > 如果在設計途中發現一直使用的某個顏色不符合標準,那麼你可以用這兩個插件批量替換顏色,節省大量逐一修改的時間。 [Able (Figma, 色彩對比度插件) <i class="fa fa-external-link"></i>](https://www.figma.com/community/plugin/734693888346260052/Able-%E2%80%93-Friction-free-accessibility) > ![](https://i.imgur.com/JFQVjfO.png) > 打開Able,可以自動比較你選擇的兩個圖層之間的色彩對比度。此外也會同步顯示不同狀態的樣貌(如字體大小、粗細),供用戶參考比較。 [Color Contrast Checker <i class="fa fa-external-link"></i>](https://www.figma.com/community/plugin/733159460536249875/A11y---Color-Contrast-Checker) 用來檢查設計稿內文字對比度是否遵守 WCAG(Web Content Accessibility Guidelines)標準,以保證使用者可以無障礙閱讀文字內容。Color Contrast Checker 的使用非常方便,喚起外掛,選中需要檢測的介面,點選 「Check」即可。 不過這款外掛也存在偶爾失效的問題,筆者還沒發現其規律和玄學。色彩對比度檢測的外掛除此之外還有三款,其中 Contrast 是筆者體驗下來比較不錯的一款,如果沒有對整個頁面內所有文字自動檢測的需求,Contrast 會更適合使用。 ![](https://i.imgur.com/BI0AbUF.gif) [Focus Orderer <i class="fa fa-external-link"></i>](https://www.figma.com/community/plugin/731310036968334777/A11y---Focus-Orderer) Focus Orderer 幫助設計師標記並測試焦點狀態(Focused)的流程和體驗是否合理,一般在網頁設計中使用。 其實筆者之前還未見過類似 Focus Order 的外掛或工具,希望未來能有更多解決或輔助無障礙設計的工具出現。一方面讓我們的設計產出更容易向無障礙標準對齊,另一方面也會影響行業內的設計師更多的關注無障礙設計領域。 ![](https://i.imgur.com/kKP71UQ.gif) [Color Blind <i class="fa fa-external-link"></i>](https://www.figma.com/community/plugin/733343906244951586/Color-Blind) 上面提到的 Color Contrast Checker 可以檢測文字的對比度,而 Color Blind 則可以將設計稿自動轉成 8 種不同型別的色盲效果,藉此我們可以進入色盲使用者的視角審視我們的設計是否合理。 ![](https://i.imgur.com/ft5931e.gif) ## 備註:政府無障礙網站官方文章 [無障礙網路空間服務網-網站無障礙檢測協助工具介紹<i class="fa fa-external-link"></i>](https://accessibility.ncc.gov.tw/Questions/Detail/4353?Category=19) [無障礙網路空間服務網-色彩對比度怎麼看?<i class="fa fa-external-link"></i>](https://accessibility.ncc.gov.tw/Questions/Detail/3261?Category=19)
