means Having been given a faint or modest shade of color, often as a thin layer over something otherwise clear or pale.

from From 'tint,' an alteration of the older 'tinct,' which traces back to Latin 'tinctus,' the past participle of 'tingere' — to dip, soak, or dye. The same Latin root colors 'tincture' and 'taint,' a small family all born from the simple act of dunking something into dye and watching the hue take hold.
