Color Filters and Light Behavior

The video tutorial explains how color subtraction works using filters. It covers the effects of primary color filters (red, green, blue) and secondary color filters (cyan, magenta, yellow) on different light colors. The tutorial also explores the outcomes when using two filters with different colors, demonstrating how certain colors are blocked or allowed to pass through, resulting in various light outputs.

What is the primary function of a color filter?

• To enhance all colors equally

• To allow only light of the same color to pass through

• To block all light

• To convert light into heat

When a red filter is used, which colors are blocked?

• All colors

• Blue and red

• Green and blue

• Red and green

What happens when cyan light passes through a red filter?

• Only green light passes through

• Cyan light passes through

• No light passes through

• Only blue light passes through

Which colors are allowed to pass through a cyan filter?

• Green and blue

• Red and blue

• All colors

• Red and green

What is the result when magenta light passes through a cyan filter?

• No light comes out

• Green light comes out

• Blue light comes out

• Red light comes out

What happens when a yellow filter is combined with a cyan filter?

• Yellow light comes out

• Red light comes out

• Green light comes out

• Blue light comes out

In a double filter setup with magenta and blue filters, what color light is seen?

• Red light

• Magenta light

• Green light

• Blue light

What is the outcome when yellow light passes through a cyan and magenta filter combination?

• Blue light comes out

• No light comes out

• Green light comes out

• Red light comes out

Which color combination results in no light passing through when using cyan and magenta filters?

• Red and green

• Green and blue

• Yellow and cyan

• Red and blue

What is the effect of using a yellow filter followed by a cyan filter on white light?

• Yellow light is seen

• Red light is seen

• Green light is seen

• Blue light is seen
