觀察到一般掛畫之掛勾遇到的問題
1.左右平衡須不斷調 2.多於掛線收納問題 3.調整按鈕不好按壓
Color hook可依據顏色調整左右掛勾長度，方便又快速。利用捲尺概念方便收納，掛畫時不會跑出多餘的線造成展覽不美觀。將按鈕設置在中間方便使用者調整長度。
掛勾為掛畫常用之工具，卻造成使用上的不便，希望藉由此設計改變這些問題，取代現有掛勾，此為跨越設計概念。

We find three problems about hook:
1.Picture is not easy to balance.2.The extra cable is not easy to hide.3.Operating the lock is not convenient.

When we use “color hook” that is an obvious button, it’s easy to press.
With 12 colors to mark its length then position is easy to identify, so the picture is easy to balance.
Use the concept of tape is easy to incorporate
Traditional hook makes us inconvenient, so we design “color hook” to solve the problems.
Color hook replaces the traditional hooks, it’s the concept about spanning.
