A simple Value Scale shows figure-ground relationships





Figure-Ground is the condition in which backgrounds tone or hue changes the visual impact of the figure resting on it. The same hue or value appears to be a different depending upon the contrast of tone or hue of the background upon which it is placed. Conversely, two different tones or hues appear to be the same when placed on contrasting grounds. Each will have an impact on how believable your art will be perceived by the viewer. Most people have difficulty perceiving “figure-ground” relationships. When the same medium toned figure is placed on varied light and dark backgrounds, it will be perceived to be as a different value.



Example: When a medium gray is placed on a near black background, the mid-gray tone appears very light. When the same gray tone is placed on a near white background, it is perceived to be very dark. But when a mid gray tone is placed on a similar value background, the contrast is minimal. Note how the same mid-tone value patch looks different when placed on backgrounds of contrasting values.
