Colombiana de Television is a one of the channels in Colombia in north-east South America. It was founded in 1972. The scariest logo is the blue logo, proof on CLG Wiki. The circles seem to zoom right out from the audience and the music sounds like NES trumpets being listened to through broken speakers watered down about twice!
High To Nightmare, the space sound effects, along with black background & chrome can scare a lot of people.
