Color
•Color is the visual effect that is caused by the spectral composition of the light emitted, transmitted, or reflected by objects.
Color originates in light. Sunlight, as we perceive it, looks colorless.
In reality, all the colors of the spectrum are present in white light.
1. All the" invisible" colors of sunlight shine on the apple.2. The surface of a red apple absorbs
all the colored light rays, except for those corresponding to red, and reflects this color to
the human eye.3. The eye receives the reflected red light and sends a message to the
brain.
When light hits the surface, the
BLUE paint ABSORBS all the light EXCEPT the blue part of the
spectrum.
There is no pure blue.

If colored paints were actually pure color- every time any two
“pure” colors of paint were mixed you would get black.
The bits of blue in the blue paint would absorb the red and yellow
light. The bits of yellow paint would absorb the red and blue light.
No light would escape from the paint, and you’d see a perfectly
black surface.

make brightest purple
make duller purple because some blue and
orange are mixed
make dullest purple, because
blue is mixed with orange and red is mixed with
green.

•HUE

•INTENSITY (or saturation)
Properties of Color
•HUE - the name of the color, the part of the color spectrum that the color belongs to: Red, orange, yellow, green, blue, or violet.

Properties of Color
•VALUE - lightness or darkness of the hue.
MUNSELL VALUES
“Normal” hues have different values.
Properties of Color
•VALUE - lightness or darkness of the hue.
•adding white produces a TINT
•adding black produces a SHADE
“ “
Properties of Color
•INTENSITY - the brightness of a color. Not to be confused with lightness, which is value.
•also called “chroma” or “saturation”.
Adding a color’s
complement will make that
color LESS INTENSE.

SHADOWS of COLORS are made by adding that color’s
COMPLEMENT.
Pink Cube Red Cube
Here, the shadowed side is more intense than the others. Only a transparent material could look like this.
The cube’s SHADOWED side must be LESS
INTENSE than the cube’s brightly-lit side.

“Color obtains in the light”
In other words:Color becomes more saturated when it’s in the
light.

Sometimes painters take this a step beyond, and paint the
shadows as the complementary color itself...

SIMULTANEOUS CONTRAST
when the color’s complement is
placed next to the color, it will look more intense.
