There is no Colorful Crayons Inc, or "Colorful Crayons" this is for a school project. Also, the website plays audio. So if you are in a place where you need quiet, or don't want audio played, than turn your volume down. (It isn't loud though)
Also, there is a secret page that contains visuals that may cause seziures. If you have epilepsy, especially photosensitive epilepsy, or you have reactions such as seziures or dizziness to flashing lights, or spinning and shaking visuals, than don't look for the secret page.
