It is acidic with a pH of 6.2.[1]
Neutral is 7, acidic is lower and basic is higher.
Litmus paper would be red.
pH paper would turn the color shown on the package. In this case, mustard.

Hydrogen peroxide is a very, very weak acid, so a 0.1 M solution should have a pH of about 6.4 (compare this to pH2.9 for ethanoic acid) - as Michael Flynn explains. However hydrogen peroxide's main activity is as an oxidising agent and as such an effective bleaching agent:
H2O2 + 2H+ + 2e- → 2H2O
Acidity (H+) helps this reaction to go forwards. If the electrons are removed from a pigment it is often the case that the oxidised pigment will be white.
