Hummingbird Feeders. Hummingbirds get the energy they need to maintain their astonishing metabolism primarily from flower nectar and the sugar water they find at feeders (here's the recipe). Think of them as miniature flycatchers, and sugar is just the fuel for getting their real nourishment.
afÂ·terÂ·imÂ·age. n. A visual image that persists after the visual stimulus causing it has ceased to act. Also called photogene. (ËÉËftÉrËÉªmÉªdÊ).
With only one bright color, the after image is usually not bothersome, but with two bright colors together, the afterimages interfere with one another, causing a visual vibration. This can be reduced by placing a neutral color between the two areas of bright colors or by making one of the colors a pastel or dark shade. Some Vibrating Color Combinations (Avoid) Below are some color combinations that can cause afterimage effects. Note: It is possible for some of these combinations to pass minimial WCAG contrast tests. However, some users may find the pairing uncomfortable.
