7. Color illusions (Chubb Illusion)
8. Color illusions (Scintillating Grid Illusion)
9. The visible spectrum
4. Color is the affiliation of the spectrum of light as it reflected or absorbed as received
by the human eye and processed by the human brain
There are three types of color class
1.Primary
2.Secondary
3.tertiary
5. Additive Primaries
By mixing red, green and blue (the additive primaries) in different
combinations and at varying levels of intensity, we can simulate the
full range of colors in nature. If the reflected light contains a mix of
pure red, green, and blue light, the eye perceives white. When no light
is present, the eye perceives black.
6. Hue: A hue is exactly the thing we mean asking “what color is it?” Exactly it’s
a another name of Color.
Tint: A tint is created by mixing a hue with white, while a shade is a mix of a
hue and black
Tone: Adding gray to a pure hue
Shade: Adding black to a pure hue
Value: The lightness or darkness of a color
Saturation: The dullness of a color
7. Color fastness test for textile material test
Wash fastness
Light fastness
Perspiration fastness
Crocking or rubbing fastness
Dry cleaning fastness
Sea water fastness
Chlorinated fastness
Water fastness

9. Hot: Intense and attention-grabbing, these schemes often include
shade of red
Warm: red is temperature by these shade yellow to create an inviting
feel that is less aggressive
Cold: Can be powerful, frigid or austere., these palettes include
bright shades of blue
Cool: yellow and red are blended with blue to create calming,
meditative and peaceful palettes
10. Chubb Illusion
Another example of color constancy: the left inner box appears darker
than the box on the right—although they’re the same color. Both squares
reflect the same amount of light into your eyes, but they still appear
different because of the context.
11. Scintillating Grid Illusion
This one is pretty trippy. Dark dots rapidly appear and disappear at the
intersections. However, if you stare at one intersection, the crossroad remains
white.
Scientists are still trying to put a finger on this one. One theory, called lateral
inhibition theory, suggests that several photoreceptors in the eye send
information to a retinal ganglion cell in the brain. As your brain interprets
these signals, the most active brain cells inhibit and reduce the activity in
neighboring cells, making them less excited. This creates an unequal black-
white contrast.
