IPA: /ˈkʌlərləsnəs/
KK: /ˈkʌlərləsnəs/
The condition of having no color or being without color.
The water appeared to have a colorlessness that made it seem pure and clear.
Colorlessness → It is formed from "color" (from Latin "color", meaning hue or pigment) and "-less" (meaning without). The word "colorlessness" means the state of being without color or hue.
Think of 'color' as the hue you see, and '-less' means without — so colorlessness is the absence of color.
