我們眼睛的視網膜中有兩種類型的細胞負責我們對顏色的感知:桿狀細胞和錐狀細胞。 錐體對顏色很敏感,在強光下效果最好。 它們以三種形式存在,每種形式的吸收光波長 (LMS) 不同。 另一方面,桿對光的強度很敏感。 在人眼中,桿狀細胞使我們能夠在黑暗中區分和檢測物體; 然而,由於它們對光的敏感度優於視錐細胞,因此我們在弱光區域感知物體顏色的能力變差。
顏色感知需要光。 當光線照射到物體上時,有些會被吸收,有些會被反射。 觀察者看到的最終顏色是由於反射波長造成的。 人眼可見的波長屬於電磁波譜的可見光部分。 顏色範圍從短波到長波,從紫色開始,然後是藍色、綠色、黃色、橙色,最後是紅色。
由於人與人之間存在輕微的生物學差異,我們感知顏色和識別顏色的方式也會有所不同。 因此,確定物體的顏色變得主觀。 比如下面這個盒子,有人說它的顏色是藍色的,有人說是綠色的,對顏色挑剔的人可能說是青色。 對於普通人來說,要準確描述物體的顏色是非常不可能的。
我們必須依靠定量方法來準確地傳達和記錄物體的顏色。 色彩空間是我們用來共同定義在顯示器上顯示、由打印機產生或可由相機捕捉的顏色範圍的術語,僅舉幾例。 常用的色彩空間包括 RGB、CMYK、HSV、CIEXYZ、CIEL*a*b*。
因此,真彩色是現實中原始圖像的準確顏色表示。
