Colossal squids have an ink sac, so they have ink. However, not much is known about the ink.

For further information, check out New Zealand's TePapa Museum site about the colossal squid: http://squid.tepapa.govt.nz/anatomy/article/colossal-squid-the-inside-story


Quote from the site: "All squid have a sac of ink inside the mantle. The ink is a dark liquid and is expelled through the funnel. If the squid meets a predator, it shoots out a cloud of ink, which hides the squid so it can escape. No one has ever seen a colossal squid producing ink so we can't be sure what the ink looks like or how the squid uses it. As there is no light down at 1,000 metres in the ocean, dark ink would be useless! It is possible that the colossal squid has luminescent ink."
