Color Explanations Better Flashcards
(11 cards)
In the RGB color model, what type of color mixing is used?
Additive mixing
RGB uses light to form colors by adding wavelengths. More light = closer to white.
Which component of HSV color space corresponds to the perceived color type?
Hue
Hue refers to the type of color we see (like red, blue, green).
Which color model is primarily used in analog NTSC television broadcasting?
YIQ
YIQ separates brightness and color info; used in old NTSC TV systems.
Which part of the human eye is responsible for color perception?
Cones
Cones in the retina detect color; rods handle night vision.
Which factors complicate color perception?
A. Spectral composition of light
B. Different spectral albedos
C. Printer type
D. Color constancy
Spectral composition of light; Different spectral albedos; Color constancy
Color perception varies with lighting, material reflection, and how our brain adjusts for consistency.
What is the main reason for introducing a separate black (K) component in CMYK color model?
To reduce ink usage and improve black stability
Adding black (K) ink reduces the need to mix full CMY, which saves ink and gives cleaner blacks.
What is the neutral point (E) in the CIE chromaticity diagram?
x=y=1/3
In the CIE chromaticity diagram, this is the ‘neutral white’ point.
Which of the following is a perceptually more uniform color space compared to CIE XYZ?
CIE Lab*
CIE Lab is designed to match human perception more uniformly than RGB or XYZ.
Which standard RGB specification is used in JPEG, PNG, and HTML?
sRGB
Standard RGB used on most displays, websites, and images.
In YUV color space, Y component represents:
Luminance
Y in YUV represents brightness (not color).
In CMY printing, what color results when C=M=Y=0?
White
In CMY, 0 ink = blank white paper (no color subtracted).
