Wonderful use of color in movies!
The use of color is celebrated a bit on the audio commentary with Joe Dante (an enthusiast of the movie) and others.
Hercules in the Haunted World (1961)
One of Mario Bava's chief personal touches seem to put together vividly saturated and pale colors, creating a weird feeling of the image being breezily hot.
The lovely production design is the real star of this film, though the ghoulishly garish colors are lend a hand.
Invaders From Mars (1953)
Suberbly colored surreal visuals and heavy film grain to boot!
