服務說明

商場展示設備器材租賃

  色彩有時在遠處可以清楚地看見,而在近處卻模糊不清,這是因為受背景色的影響。清楚可辨認的色叫視認度高的色,相反叫視認度低的色。視認度在底色和圖形色的三屬性差別大時增高,特別是在明度差別大時更會增高,并且受到當時照明狀況和圖形大小的影響。

  1、色彩的前進與后退。在相同距離,有的色比實際距離看起來近;而有的色則看起來比實際距離遠;從色相上看,暖色系的色為前進色,冷色系的色為后退色;明亮色為前進色,暗灰色為后退色;彩度高的色為前進色,彩度低的色為后退色。

  2、色彩的膨脹和收縮。同樣面積的色彩,有的看起來大些,有的則小些。明度、彩度高的色看起來面積膨脹;而明度、彩度低的色則面積縮小。暖色為膨脹色,冷色為收縮色。
