Water is colorless because its components, hydrogen and oxygen, are colorless. Water can be colored with food coloring and other means, however it's not the water itself that is colored but the particles of color suspended within.
Helium is a light colourless gas that does not burn
Oxygen.
Colourless, or slightly white
Several reasons, the first being that if air had an odour, other smells, including those that alert us to danger, would be harder to detect. Also, our sense of taste would be impaired as a valuable part of that taste is smell. this could prove dangerous if we were to eat something that we otherwise would not due to taste, and it proved toxic. As for it being colourless, if air had a colour, it would be much like fog in impairing vision. Imagine for a second that the air in front of your face was red. The air pressure would determine the depth of colour, however the distance that you could see through would always be less than it would be if colourless.
Acetylene is a colourless, combustible gas with a distinctive odour.When acetylene is liquefied, compressed, heated, or mixed with air, it becomes highly explosive.
Almost all of the principal gases in the atmosphere are colourless. Hence we see the air as colourless.

air
air cannot be seen because it is colourless
It's colourless. When it absorbs oxygen from the air, it turns purple. It can be used in this way to calculate the amount of oxygen in air. colourless → + oxygen → purple (just an example, not a proper format)
Oxygen.
They are the two main constituents of the air and, as you will notice, they are colourless.
it is colourless tasteless odourless lighter than air & is highly flammable
colourless is farbloss
Balloons are usually filled with air. It is a colourless gas. There are other colourless gas options: helium, hydrogen, methane. Coloured gas options (chlorine, bromine) are generally reactive with the rubber or fabric used in balloon manufacture and are undatisfacoty as balloon fillers.
Are acids colourless? Yes they are. So acid rain is colourless
