Value

1. How does value relate to light and form (value structure)

2. How does value relate to local color (Hue/Value/Chroma)

Simultaneous Contrast: We overstate the difference in adjacent values

Value Structure

• Clear hierarchy of lights and darks

• Clear and consistent light mass and shadow mass

• Lightest part of the shadow mass is still darker than the darkest part of the light mass, and visa versa

Color is broken down into 3 factors

• Hue - What color is it (Red, Purple, Magenta, Green)

• Chroma - How intense is the color (how purple is that purple)

• Value - How light or dark is the color (a Shade is a color + black, a Tint is a color + white)

Purple is the darkest color in value at its highest ChromaYellow is the lightest color in value at its highest Chroma

Colors at their most saturated, from dark to light, are Purple, Blue, Green, Red, Orange, Yellow

A really purply purple is very dark A really yellowy yellow is very light
