Question

Do any gas have color?​

Answer 1

Answer:

Actually, gases aren't invisible: many are quite brightly coloured. For example, nitrogen dioxide is brown-y orange, chlorine has a yellowish green hue and iodine vapour is a vivid purple

Answer 2

Answer:

Gas is invisible. Thus, does not exhibit color. A substance starts to be visible when the attractive forces between them become somewhat significant as in its colloidal form, liquid state and solid state.
