Subtractive Theory of Color, Continued
Color influence
Three factors affect hue, value, and intensity when you see a colored object.
These three factors are (1) the local color of the object, (2) the light source
which illuminates it, and (3) any color reflecting surfaces near the object. By
understanding what happens to color when influenced by other colors, you
can use pigments to more effectively portray natural color.
Local color
Local color is the color of an object that is not modified by light, reflection,
weather, or distance. Local color is sometimes referred to as true color.
Even the spot of color in figure 2-21 reflects some light that creates
highlights.
Figure 2-21 is a spot of color.
