The present invention relates to a web substrate comprising an activatable colorant and at least one deformed region. A first activated color region is produced in the web substrate upon exposure to a first external stimulus and a second activated color region is produced within the first activated color region upon exposure to a second external stimulus. The second activated color region coincides with the deformed region.
