Colourless.

Explanation:

#HNO_3# is nitric acid, which is a colourless liquid.

The substance that has a reddish colour (or at least it gives off red fumes) is "Red fuming nitric acid" but that is a blend of 84% #NHO_3#, 13% #N_2O_4# and a couple of percent water. It is used for rocket fuel applications, and is quite different from plain nitric acid.
