品牌識別設計理念

日大門窗品牌以門窗與自然的關係連結性為發想點，以圓形象徵太陽的溫暖，一如日大公司品牌名稱；而白色菱形圖像設計猶如是從雲隙照射下來的陽光；透過藍、白、菱形相接的視覺意象呈現手與手相互緊握貌，象徵守護家園的力量。在品牌色上採用日光橘、天空藍、雲朵白，並將品牌識別系統導入辦公空間及整體形象，為日大門窗塑造欣欣向榮、團結向上的企業榮景。

The brand design initiates from the relationship between doors, windows and nature. The round symbolizes the warmth of the sun just like the meaning of the company name. White rhombus is the sun shining through the gap. The imagery of blue, white, and rhombuses connecting is holding hands tightly to symbolize the power to protect homes. In color, daylight orange, sky blue and white clouds are also used to introduce the brand recognition system into the office space and overall image. The design shapes a prosperous and united enterprise for the doors and windows of RIDA.
