Ch. 9
-Unique/Pure Colours:
red, yellow, green, blue
Red= Long wavelength
yellow=medium
blue=short wavelength
- Saturation:
intensity of the light
can be lighter/dimmer
less saturated colour has more white
Hue:
-Chromatic:
red/green/blue
occur when come wavelengths are reflected more than others
-Selective reflection
-Achromatic:
white gray black
light is reflected equally across the spectrum
- Reflectance curves:
Plots of the % of light vs. Wavelength
X AXIS: WAVELENGTH
Y AXIS: REFECTANCE
- Selective transmission:
Canberra juice selectively transmits long wave light that appears red.
Lime juice selectively transmits medium wave
- Transmission Curves:
light transmitted vs. wavelength
-Additive Colour Mixture:
mixing lights involves adding up all the wavelengths of each light
-Subtractive Colour Mixture:
mixing paints
wavelengths are absorbed
- Colour adds contrast
- Retina sensitive to 400-700nm on the Electromagnetic spectrum
- The colours of objects are associated with what wavelengths are reflected (for opaque) and
transmitted (for transparent)
- Mixing lights causes more wavelengths to be reflected (each adds)
-Mixing paints causes fewer wavelengths to be reflected (each subtracts/absorbs)
